Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to an adjustable footwear,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a shoe, and more particularly, to a shoe capable of adjusting a heel height selectively according to an ignition environment.

In general, shoes have been developed to be worn to protect their feet, but as their quality of life has increased recently, the perception of shoes has also changed a lot.

Shoes can be classified into various categories such as shoes, sneakers, hiking boots, and multipurpose shoes depending on the purpose. The shoe is mainly made of natural or artificial leather and has an upper part, and a sole having a predetermined height is mounted on the lower part of the sole part for protecting the sole part.

Among the shoes, women's shoes can be classified into various forms according to the heights and types of heels. In the case of high-heeled shoes with a high heel, It is true.

However, since the heel of the existing high heel shoes has a fixed length, there is a problem in that it is necessary to take a lot of inconvenience in order to wear the high heel until the first time he goes home.

In particular, when wearing high-heeled shoes (high-heeled shoes) for a long time, the ankle and knee joints are given a load, and the weight is transferred to the forefoot region of the foot, The knee and the pelvis are adversely affected, causing a problem of lumbar lordosis.

In addition, since the existing heel shoes are not easy to separate the heel fixed to the soles, if the user wants to wear a low-heeled shoe, a low-heeled shoe must be purchased separately, and troublesome and inconvenient .

In addition, the conventional high-heeled shoes have a problem in that their weight is difficult to be dispersed because of their small contact area in contact with the ground surface (in particular, the contact area of the heel area is small). As a result, there is a problem that the feeling of wearing is lowered and it is difficult to ensure a comfortable walking, and the energy efficiency of the body is lowered when worn for a long period of time, thereby increasing fatigue of the feet.

Recently, there have been various studies on shoes that can use one shoe for multipurpose use, disperse weight to ensure comfortable walking, and reduce fatigue of foot. However, .

An object of the present invention is to provide a shoe-adjustable shoe which can be used for various purposes by selectively adjusting the heel height of the shoe.

It is another object of the present invention to provide a shoe which can be comfortably walked by dispersing a load and which can lower the fatigue of the foot and which can be adjusted in heel height.

Another object of the present invention is to provide a shoe which can contribute to the upgrading of a product and which can improve the satisfaction of the consumer.

According to another aspect of the present invention, there is provided a footwear comprising: a sole part for supporting a sole of a user; a carapace provided on an upper part of the sole; The sole is provided with a fixed heel provided at a lower portion of the shoe so as to be movable at a lower portion of the shoe so as to have different heel heights, and a variable heel part having a movable heel, so that the heel height can be selectively adjusted according to the use environment, and comfortable walking can be ensured.

More specifically, the moving heel is provided movably in a high-heel mode disposed at a lower portion of the fixed heel and contacting the ground, and a low-heel mode disposed at a side of the fixed heel and contacting the ground, The height of the variable heel portion is lower than when the movable heel is disposed in the high-heel mode.

This is achieved by changing the heel height of the shoe to different conditions according to the use environment and the user's physical condition, so that one shoe can be used to emphasize the legs of the woman and enhance the heel mode and comfortable walking And the low-heel mode that can be guaranteed.

In this manner, by moving the moving heel at the bottom of the sole, the high heel height can be ensured in the high heel mode, and the contact area can be increased in the low heel mode, And the walking stability can be achieved.

Above all, it is preferable that the contact area of the variable heel portion is increased in a state where the movable heel is disposed in the low-heel mode. As described above, in a general walking condition (low-heel mode), the contact area of the shoe is increased to disperse the ground pressure according to the body weight, so that a more comfortable and stable walking can be ensured and the fatigue of the foot can be lowered .

The structure capable of increasing the contact area of the variable heel portion in the low-heel mode can be variously changed according to the required conditions and design specifications. As an example, in the low-heel mode, the moving heel may be placed in contact with the ground, while at the same time the bottom of the fixed heel may be in contact with the ground. like this,

When the movable heel is separated in the low-heel mode, when the bottom surface of the fixed heel exposed is in contact with the ground, the contact area of the variable heel portion with respect to the ground surface can be increased. Furthermore, since the bottom surface of the fixed heel exposed as the movable heel is separated can have a larger area than the bottom surface of the movable heel (based on the high-heel mode), a wider contact area can be ensured.

Preferably, in the high-heel mode, the front surface of the moving heel toward the front of the sole may be formed to have a larger area than the bottom surface of the moving heel contacting the ground, and in the low heel mode, It can be placed on the bottom surface and brought into contact with the ground. Such a structure further increases the contact surface area of the variable heel portion with respect to the ground in the low-heel mode, thereby ensuring more stable and comfortable walking.

More preferably, the front surface of the moving heel contacting the ground in the low-heel mode may be flush with the bottom surface of the fixed heel. Such a structure allows the contact by the moving heel and the fixed heel to be made on the same plane with respect to the ground, so that the load distribution on the heel portion where the weight is heavily loaded can be more effectively achieved.

Further, a curved surface portion may be formed on the bottom surface of the shoe sole, and the rear surface of the moving heel facing the curved surface portion in the low-heel mode may be formed as a curved surface corresponding to the curved surface portion. Such a structure allows the soles and moving heels to be more effectively adhered in the low-heel mode, thereby minimizing the flow and heterogeneity due to the moving heel during walking.

Further, a reinforcing member may be provided so that the movable heel is disposed in the low-heel mode and disposed between the fixed heel and the movable heel. The reinforcing member prevents deformation and breakage of the variable heel portion in the low-heel mode and improves the structural stability of the forming heel portion.

Preferably, the reinforcing member may be formed of a material having higher strength than at least one of the fixed heel and the moving heel. Such a structure is characterized in that the reinforcing member is formed of a material having a higher strength than the fixed heel and the moving heel and is disposed between the fixed heel and the movable heel so as to be exposed to the ground in the low heel mode, The end surface of the reinforcing member can be brought into contact with the ground surface at a higher pressure than the fixed heel and the moving heel, thereby making it possible to perform a function of preventing slippage such as ordinary eigen.

The reinforcing members may be provided in various ways depending on the required conditions and design specifications. For example, the reinforcing member may be mounted on the upper surface (on the basis of the high-heel mode) of the moving heel with the moving heel disposed in the high-heel mode, and when the moving heel is separated from the fixed heel and disposed in the low- May be disposed between the heel and the moving heel. In some cases, it is possible to mount the fixing member on the front surface of the fixed heel. Alternatively, the reinforcing member may be provided in a structure separable from the fixed heel and the movable heel. In the high-heel mode, the reinforcing member may be carried in a separated state and then disposed between the fixed heel and the moving heel only in the low-heel mode.

In order to improve the grounding and stability of the variable heel, a first outsole may be provided on the bottom surface of the fixed heel, and a second outsole may be provided on the front surface of the moving heel toward the front of the sole in the high heel mode , The first outsole and the second outsole may contact the ground when the moving heel is placed in the low-heel mode.

In addition, a visually distinguishable identification part can be formed on the surface of at least one of the fixed heel and the moving heel.

The identification part can be visually discernible in various ways depending on the required conditions and design specifications. In one example, the identification can be visually identified by having at least one of visually discernible hues and materials. Especially, it is important to make the shoes fit in the right size, but the external design is as important as that. For example, according to a survey of buyers by a company, the first thing to consider when purchasing a product is 'design'. The result is that the external design of the product greatly influences the purchase of the product. Conventionally, the heel of the shoe itself has a single design characteristic. However, since different design characteristics can be expressed in the high-heel mode and the low-heel mode by using the identification part in the present invention, the design characteristic of the product can be improved The present invention can contribute to the upgrading and differentiation of the product, and it is possible to enhance the satisfaction of the consumer.

In addition, an elastic contact portion in which the user's foot is contacted may be formed on the inner surface of the skin. The resilient contact portion minimizes the user ' s foot slippage in the shoe, thereby preventing the shoe from easily unintentionally peeling off.

According to another preferred embodiment of the present invention, the heel-adjustable footwear includes a variable heel portion having a sole portion, a carapace, a fixed heel, and a moving heel, wherein the moving heel is mechanically connected to the fixed heel, Or to move to a low-heel mode.

Here, the moving heel is mechanically connected to the fixed heel, it can be understood that the movable heel and the fixed heel are connected in a relative flow possible state, and the mechanical connection between the moving heel and the fixed heel is And can be variously changed.

In one example, the moving heel can include a first rotating heel rotatably connected to the stationary heel, and a second rotating heel rotatably connected to the first rotating heel, wherein in the low heel mode, At least one of the second rotary heels may be in contact with the ground, and in the low-heel mode, the contact area of the shoe may increase as one of the rotary heels contacts the ground.

As described above, according to the present invention, it is possible to selectively use the heel height of the shoe for a multipurpose purpose.

Particularly, according to the present invention, it is possible to satisfy both the high-heel mode which can raise the legs of women by using one shoe and the low-heel mode which can guarantee the comfortable walking, and the self-

Furthermore, the moving heel can guarantee a high heel height in the high-heel mode, and the low-heel mode can contact the ground and increase the contact area in the low-heel mode, so that a single shoe can satisfy both the design characteristics and the walking stability.

In addition, according to the present invention, it is possible to disperse the ground pressure according to the body weight over a wider area, to ensure a comfortable and stable walking, and to reduce fatigue of the foot.

Further, according to the present invention, the structural stability of the variable heel portion can be improved by using the reinforcing member, and stable walking can be performed without slip on the ice sheet and slippery ground in the winter season.

Further, according to the present invention, it is possible to minimize unintentional peeling of shoes when walking by using the elastic contact portion.

Another object of the present invention is to provide a shoe which can contribute to the upgrading of a product and which can improve the satisfaction of the consumer.

FIG. 3 is a view for explaining an example of use of a shoe with adjustable heel height according to the present invention, and FIG. 4 is a view illustrating a shoe with a heel height adjustable according to the present invention, FIG. 5 is a view for explaining the joining structure between the fixed heel and the moving heel, which is a heel-adjustable shoe according to the present invention.

Referring to FIGS. 1 to 5, the heel-adjustable shoe according to the present invention includes a sole 100, a skin 200, and a variable heel 300.

The sole part 100 is provided to support the sole of the user.

The shoe sole 100 may be configured to support a user's sole in various structures according to required conditions and design specifications. For example, the sole 100 may be provided to support the sole of the user as a whole. In some cases, it is also possible that the sole portion supports only the edge portion of the user's soles or partly supports the sole of the user.

The shoe sole 100 may be provided in a single layer structure or may be provided in a multi-layer structure of different materials, and the present invention is not limited or limited by the material and the laminated structure of the shoe sole 100.

The upper part of the skin 200 is provided on the upper part of the sole 100 to support the user's foot side. Here, the cape skin 200 supports the user's foot surface. The cape skin 200 may be a concept that includes both the partial support of the foot side of the user or the entire structure of the user's foot .

The cape skin 200 may be formed of ordinary leather, artificial leather, synthetic resin, or mesh, and the present invention is not limited or limited depending on the material and characteristics of the cape skin 200.

The variable heel part 300 is provided so that the sole 100 has a predetermined rear heel height and a fixed heel 310 and a moving heel 320 movable heel.

The fixed heel 310 is fixed to the rear bottom of the sole 100 and the moving heel 320 is movable in the lower portion of the sole 100 so that the sole 100 optionally has different heights And is brought into contact with the ground.

The moving heel 320 is movably provided at the lower portion of the sole 100 so that the moving heel 320 can be selectively disposed at different positions in the lower portion of the sole 100 Can be understood. The movable heel 320 selectively has different heel heights because the movable heel 320 is disposed at a different position from the heel 100 so that the heel of the sole 100 And the height of the rear axle of the sole portion 100 corresponds to the total height of the variable heel portion 300. [

The moving heel 320 may be provided in various structures that are movably provided at the lower portion of the shoe sole 100 and can contact the ground. For example, the moving heel 320 is movable in a high-heel mode disposed at a lower portion of the fixed heel 310 and in contact with the ground, and a low-heel mode disposed at the side of the fixed heel 310 and contacting the ground. And the height of the variable heel portion 300 (the height of the rear axle of the sole 100) is smaller than the height of the movable heel 320 when the movable heel 320 is placed in the low heel mode Lower.

As described above, according to the present invention, the moving heel 320 can be selectively moved so that one shoe can be used by switching to a high-heel mode or a low-heel mode according to the use environment.

The high heel mode and the low heel mode switching using the moving heel 320 can be implemented in various ways according to required conditions and design specifications. For example, the moving heel 320 may be spaced apart from the fixed heel 310 to move into a high-heel mode or a low-heel mode.

A state where the moving heel 320 is disposed in the high heel mode, that is, a state where the moving heel 320 is disposed below the fixed heel 310, may be a normal state such as a fixed pin, a hook, The movable heel 320 can be separated from the fixed heel 310 by being separated from the fixed heel 310 by releasing the fixed state by the fixing member.

Referring to FIG. 5, a plurality of fixing pins 326 may protrude from the upper surface of the movable heel 320 (on the basis of the high-heel mode) A plurality of first fixing holes 316a may be formed on the front surface of the fixing heel 310 to couple the fixing pins 326 in the low heel mode, 316b may be formed. Therefore, in the high-heel mode in which the moving heel 320 is disposed below the fixed heel 310, the fixing pin 326 can be inserted and fixed in the first fixing hole 316a.

Here, when the movable heel 320 is separated from the fixed heel 310, the mechanical connection between the fixed heel 310 and the movable heel 320 is released.

The structure and shape of the fixed heel 310 and the movable heel 320 can be variously changed according to required conditions and design specifications. Hereinafter, the moving heel 320 is formed to have a gradually narrower width from the upper end to the lower end based on the high-heel mode, and the fixed heel 310 corresponds to a thick part of the moving heel 320 from the upper end to the lower end An example formed by a width will be described. In some cases, the fixed heel and the moving heel may be formed to have opposite shapes, or may have other geometric structures.

Further, when the moving heel 320 is placed in the low-heel mode (see FIG. 2), the contact area of the variable heel portion 300 with respect to the ground is increased so that the moving heel 320 is placed in the high- . As the contact area of the variable heel part 300 contacting the ground increases, the weight of the user can be dispersed through the wide contact area by the variable heel part 300, so that a more comfortable and stable walking can be assured , And fatigue of the foot can be lowered.

Similarly, a state in which the moving heel 320 is disposed in the low-heel mode, that is, a state in which the moving heel 320 is disposed on the side (for example, the front side) of the fixed heel 310, A hook, a bolt, or the like, and the movable heel 320 may be separated from the fixed heel 310 by releasing the fixed state by the fixing member. In some cases, the arrangement of the fixed heel and the movable heel in the high-heel mode and the low-heel mode may be configured to be a normal sliding-engagement mode.

Referring to FIG. 5, a plurality of fixing pins 326 may protrude from the upper surface of the movable heel 320 (on the basis of the high-heel mode) A plurality of first fixing holes 316a may be formed on the front surface of the fixing heel 310 to couple the fixing pins 326 in the low heel mode, 316b may be formed. Therefore, in the low-heel mode in which the movable heel 320 is disposed in front of the fixed heel 310, the fixed pin 326 can be inserted and fixed in the second fixed hole 316b. In addition, the first outsole 312, which will be described later, may be coupled to the bottom surface of the fixed heel using a first fixing hole formed in the bottom surface of the fixed heel in the low-heel mode.

The structure capable of increasing the contact area of the variable heel part 300 in the low-heel mode can be variously changed according to required conditions and design specifications. For example, when the moving heel 320 is separated from the fixed heel 310 and placed in the low-heel mode, the bottom surface of the fixed heel 310 may be in contact with the ground.

Referring to FIG. 4, the front surface of the moving heel 320, which is disposed to face the front of the sole 100 in the high-heel mode, is disposed in contact with the ground in the low-heel mode. Accordingly, when the bottom surface of the fixed heel 310 exposed to the movement of the movable heel 320 in the low-heel mode is brought into contact with the ground, the contact area of the variable heel portion 300 with respect to the ground increases (Z2 '> Z2) .

In addition, in the low-heel mode, not only the contact area by the variable heel part 300 increases (Z2 '> Z2) but also the contact area where the bottom surface of the sole part 100 (bottom surface of the forefoot part) '> Z1), it is possible to more effectively disperse the ground pressure due to the weight.

In the present invention, the front surface of the moving heel 320 refers to the front surface of the moving heel 320 disposed in the high heel mode, and the front surface of the moving heel 320 In the low-heel mode, the bottom surface of the moving heel 320 is switched. In practice, in the low-heel mode, the front side (low-heel mode reference) of the moving heel 320 will be the underside (based on the high-heel mode) of the moving heel 320, (The high-heel mode reference) of the moving heel 320 comes into contact with the ground in a state where the moving heel 320 is placed in the low-heel mode.

Preferably, in the high-heel mode, the front surface of the moving heel 320 facing the front of the sole 100 may be formed to have a relatively larger area than the bottom surface of the moving heel 320 contacting the ground, The front surface of the moving heel 320 may be disposed on the bottom surface of the moving heel 320 and contact the ground surface. Such a structure further increases the contact surface area of the variable heel portion 300 with respect to the ground in the low-heel mode, thereby ensuring more stable and comfortable walking.

More preferably, the front surface of the moving heel 320 contacting the ground in the low-heel mode may be flush with the bottom surface of the fixed heel 310. Such a structure allows the contact by the moving heel 320 and the fixed heel 310 to be made on the same plane with respect to the ground, so that the load distribution at the heel portion where the weight is heavily weighted can be made more effective .

3, the moving heel 320 may be disposed in a low-heel mode to increase the contact area of the shoe with respect to the ground when walking on a sloping slope (e.g., a downhill slope or an uphill slope) By distributing the ground pressure according to the weight, more stable walking is possible.

A curved surface portion 102 having a predetermined curvature may be formed on the bottom surface of the shoe sole 100 and a rear surface of the moving heel 320 facing the curved surface portion 102 in the low heel mode May be formed as a curved surface corresponding to the curved surface portion 102. [ Such a structure allows the soles 100 and the moving heel 320 to be more effectively attached in the low-heel mode, thereby minimizing the flow and heterogeneity of the moving heel 320 during walking.

Further, in the embodiment of the present invention, the front side of the moving heel 320 contacting the ground in the low-heel mode is described as being configured to be in contact with the ground entirely, but in some cases, It is also possible that the front surface of the moving heel partially contacts the ground.

In the embodiment of the present invention, the fixed heel 310 and the moving heel 320 are all in contact with the ground in the low-heel mode. In some cases, the movable heel is in contact with the ground It is also possible to configure it not to. That is, in the high-heel mode, the front surface of the moving heel 320 facing the front of the soles 100 is formed to have a larger area than the bottom surface of the moving heel 320 contacting the ground. In the low- The front surface of the stationary heel 320 may be disposed on the bottom surface of the moving heel 320 so that the bottom surface of the stationary heel 310 does not contact the ground. Since the front surface of the moving heel 320 contacting the ground in the low-heel mode has a larger area than the bottom surface of the moving heel 320, even if the bottom surface of the fixed heel 310 does not touch the ground surface, The contact area of the variable heel portion 300 with respect to the ground can be increased.

2, a reinforcing member 330 may be provided to be disposed between the fixed heel 310 and the moving heel 320 with the movable heel 320 disposed in the low-heel mode.

The reinforcing member 330 prevents deformation and breakage of the variable heel part 300 in the low-heel mode and improves the structural stability of the forming heel part.

Preferably, the reinforcing member 330 may be formed of a material having a higher strength than at least one of the stationary heel 310 and the moving heel 320. For example, the reinforcing member 330 may be formed of a common metal material.

In addition, the reinforcing member 330 plays a role of enhancing the structural stability of the variable heel part 300 and serves as an eisen to prevent slipping on the winter ice sheet and slippery ground. That is, the reinforcing member 330 is formed of a material having a strength higher than that of the fixed heel 310 and the movable heel 320, so that the reinforcement member 330 is exposed between the fixed heel 310 and the movable heel 320 in a low- Since the end portion of the reinforcing member 330 can be brought into contact with the ground surface at a higher pressure than the fixed heel 310 and the movable heel 320 when the user's weight is applied to the variable heel portion 300 during the walking, Can be prevented.

The reinforcing member 330 may be provided in various ways depending on the required conditions and design specifications. For example, the reinforcing member 330 may be mounted on the upper surface (on the basis of the high-heel mode) of the moving heel 320 while the moving heel 320 is positioned in the high-heel mode, The reinforcing member 330 may be disposed between the stationary heel 310 and the moving heel 320. In this case, In some cases, it is possible to mount the fixing member on the front surface of the fixed heel. Alternatively, the reinforcing member may be provided in a structure separable from the fixed heel and the movable heel. In the high-heel mode, the reinforcing member may be carried in a separated state and then disposed between the fixed heel and the moving heel only in the low-heel mode.

In order to improve the grounding and stability of the variable heel part 300, a first outsole 312 may be provided on the bottom surface of the fixed heel 310, and in the high heel mode, A second outsole 322 may be provided on the front side of the moving heel 320 facing the first outsole 312 and the first outsole 312 and the second outsole 322 may be in contact with the ground when the moving heel is disposed in the low- .

Particularly, it is preferable that the first and second outsole 312 and 322 are formed of a material suitable for being in contact with the ground, such as a material having excellent anti-slip characteristics, abrasion resistance, restoring force and shock absorbing property.

In the embodiment of the present invention, the first and second outsole 312 and 322 are integrally connected to the variable heel part 300. However, in some cases, the moving heel may be placed in the low heel mode At least one of the outsole members may be separately coupled to the moving heel and the lower portion of the fixed heel (the front surface of the movable heel and the bottom surface of the fixed heel on the basis of the high-heel mode) using a fastening member or a sliding coupling method.

On the other hand, a visually distinguishable identification part can be formed on the surface of at least one of the fixed heel 310 and the movable heel 320. [

The identification portion can be visually discernible in various ways according to the required conditions and design specifications. In one example, the identification can be visually identified by having at least one of visually discernible colors and materials. Hereinafter, an example will be described in which an identification part having different colors, which are visually distinguishable, is formed on the surfaces of the fixed heel 310 and the moving heel 320, respectively.

Especially, it is important to make the shoes fit in the right size, but the external design is as important as that. For example, according to a survey of buyers by a company, the first thing to consider when purchasing a product is 'design'. The result is that the external design of the product greatly influences the purchase of the product. Conventionally, the heel of the shoe itself has a single design characteristic. However, since different design characteristics can be expressed in the high-heel mode and the low-heel mode by using the identification part in the present invention, the design characteristic of the product can be improved The present invention can contribute to the upgrading and differentiation of the product, and it is possible to enhance the satisfaction of the consumer.

In addition, an elastic contact portion 220 may be formed on the inner surface of the cape skin 200 to allow the user's feet to contact.

The elastic contact portion 220 minimizes the slippage of the user's foot in the shoe so that the shoe can be prevented from being inadvertently easily peeled off.

The elastic contact portion 220 may be provided in various positions and forms that the user's feet can contact, and the present invention is not limited or limited by the forming position and structure of the elastic contact portion 220. Preferably, the resilient contact portion 220 may be formed on the inner surface of the cape skin 200 so that the elastic contact portion 220 can be brought into contact with the foot, for example, the heel portion of the user's foot or the side portion of the foot.

The elastic contact part 220 may be formed of a general elastic material capable of preventing slipping, and the material and characteristics of the elastic contact material may be variously changed according to required conditions and design specifications. For example, the elastic contact portion 220 may be formed of a conventional silicon or rubber material.

Meanwhile, FIG. 6 is a view illustrating a shoe with adjustable heel height according to another embodiment of the present invention. In addition, the same or equivalent portions as those in the above-described configuration are denoted by the same or equivalent reference numerals, and a detailed description thereof will be omitted.

5, the heel-adjustable shoe according to another embodiment of the present invention includes a shoe having a sole 100, a skin 200, a fixed heel 310 'and a movable heel 320' The moving heel 320 may be mechanically coupled to the stationary heel 310 to move into a high-heel mode or a low-heel mode.

Here, the moving heel 320 'is mechanically connected to the stationary heel 310', it can be understood that the moving heel 320 'and the stationary heel 310' are relatively movably connected, The mechanical connection between the moving heel 320 'and the fixed heel 310' may be varied in various ways depending on the required conditions and design specifications.

For example, the moving heel 320 'may include a first rotating heel 320' rotatably connected to the fixed heel 310 ', and a second rotating heel 320' rotatably connected to the first heel 320 ' And may include a second rotating heel 330 ', wherein at least one of the first rotating heel 320' and the second rotating heel 330 'is in contact with the ground in the low-heel mode. In some cases, it is possible to configure the first and second rotary heels to contact the ground in the low-heel mode. Alternatively, it is possible that the moving heel includes three or more rotating heels, and the present invention is not limited by the number and shape of the rotating heels.

The first and second rotating heels 320 'and 330' may be rotatably connected using conventional hinge means and the first and second rotating heels 320 'and 330' The present invention is not limited to or limited by the rotating connection structure of FIG.

Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. It will be understood that the present invention can be changed.
