る。 On the other hand, shoe insoles described in Japanese Utility Model Publications No. 49-112455 and Japanese Utility Model Publication No. 7-12675, and shoe soles described in Japanese Utility Model Publication No. 34-12553 are also known. However, these shoe insoles,
Since the sole of the shoe does not have a structure based on exercise physiology, it has the disadvantage of causing loss of power supply during walking. This idea is that when walking, the heel touches the ground first, the load is applied concentrically around the point of contact, and then the entire sole of the foot lands, and then the tip of the first metatarsal bone (the so-called big toe). base) and the fifth
The center of the load shifts to the treading area, which is made up of a straight line surrounding the tip of the midbone (the base of the little finger).
(Bending between the stepping part and the toe part) The stepping part and the heel part play a different role in exercise physiology, kicking the ground with the toe part, and the direction of movement of the foot during walking and running is determined by the As shown in Figure 4, always follow the foot length line c of the insole.
This is based on the fact in exercise physiology that the direction is not necessarily the same, and the fact in exercise physiology that stability is required in the heel part when walking and running.
That is, if the stepping part and the toe part cannot be bent easily, extra force will be required and an extra burden will be placed on the foot. When provided in a shoe insole, the angles θ 1 and θ 1 ' between the protrusion and the direction of foot movement f are not right angles, as shown in FIG. The focus was on That is, in the insole of a shoe having a sole shape in which a plurality of striated projections and striated grooves are provided alternately on the back surface, a central projection is provided at the heel contact point of the heel part, and the striated projections and striated grooves are By forming concentric circles around the central protrusion, the stepping part, which consists of a peripheral zone of a straight line connecting the first metatarsal tip installation position and the fifth metatarsal tip installation position, has an arc-shaped heel. The above object is achieved by providing an insole for shoes characterized by forming circular and arcuate linear protrusions and grooves in the upper part, and having the upper surface curved upward on the left and right sides in the longitudinal direction. aim to achieve.

品質を得ることができる。 The following description will be made based on the illustrated embodiment. 1 is made of a foam material such as polyurethane, polyethylene, rubber, EVA, styrene, etc., and has a sole-shaped insole, and has a first metatarsal tip installation position 2 and a fifth metatarsal tip installation position 3. The surrounding area of the connecting straight line a is the stepping part 4
and the heel contact point b (normally from the rear end of the insole main body 1)
15 to 17% point) is defined as the heel portion 5. The stepping part 4 is provided with alternating arc-shaped linear grooves 6 and linear protrusions 9 that intersect approximately at right angles to a line drawn in the longitudinal direction of the insole main body (referred to as foot length line c, which is an imaginary line). Provide multiple. The heel portion 5 is provided with a central protrusion 12 at the grounding point b of the heel, and striated protrusions 10, 11 and striated grooves 7, 8 are alternately formed in concentric circles centered on the central protrusion 12, forming a circular shape. and arc-shaped striated protrusions 10,
11. Form the linear grooves 7 and 8. At this time, the arc of the linear groove 6 or the linear protrusion 9 of the treading portion 4 is
It passes through the vicinity of the metatarsal tip installation position 2 and the vicinity of the fifth metatarsal tip installation position 3. The linear grooves 6, 7, and 8 are all curved and parallel to each other, and as a result, a plurality of linear protrusions 9 are formed on the treading part 4 and the heel part 5 on the lower surface of the insole main body 1. , 10, 11 are formed. The shapes of the linear grooves 6 and the linear protrusions 9 of the stepping portion 4 are determined by the volume ratio of the former 6 to the latter 9 and the correlation with the hardness of the insole main body 1. Normal hardness
When using a material with an angle of 50° to 20°, suitable quality can be obtained by setting the volume ratio of the linear grooves 6 to the linear protrusions 9 to be approximately 1.2 to 2.0.

に寄与する。 In the illustrated example, the upper surface of the insole main body 1 is formed into a so-called cup inner sole shape in which the left and right sides in the longitudinal direction are slightly curved upward. In addition, d is a toe part, and e is a non-stepping part. In this invention, a linear groove 6 and a linear projection 9 formed in an arc shape on the tread portion 4 are provided.
Since they are arranged so as to intersect the foot length line c at a substantially right angle, they adapt well to the bending of the foot. That is, even if the direction of foot movement f deviates from the foot length line c by a certain angle as shown in FIG. Since θ 2 and θ 2 ' are close to right angles, the tread force at the treading part is better,
The power supply loss is reduced, and since there are arc-shaped linear grooves and linear protrusions between the toe part d and the treading part 4 that are similar to the curved shape around the treading part, the difference between the two is reduced. Bending is easy and the bottom has a good bounce. The heel portion 5 is provided with a central protrusion 12 at the heel grounding point b, and the striated protrusions 10, 11 and the striated grooves 7, 8 are alternately formed in concentric circles centered on the central protrusion 12. It has a high degree of shock absorption when running and walking, and the heel is held stably, and it is also highly elastic, making it comfortable to wear. In addition, since the linear grooves 6, 7, 8 are formed, the linear protrusions 9, 10, 1 will be removed when subjected to a running load.
Due to the crushing deformation in step 1, air is discharged and sucked through the gap between the inner wall of the shoe and the foot, so there is no feeling of stuffiness. Furthermore, since the linear grooves 6, 7, and 8 are provided, less material is required, which contributes to weight reduction and cost reduction.

ある。 Therefore, this invention has the following effects: it is lightweight, does not feel stuffy, has a high degree of absorption of impact on the ground, has little loss of power supply when walking, and has good bottom bounce when walking. In addition, since the heel portion has the striated grooves and striated protrusions formed in a plurality of concentric circles centered on the heel contact point, the heel has the effect of further improving the grounding stability of the heel. Furthermore, since the left and right sides of the upper surface of the insole in the longitudinal direction are curved upward, it matches the three-dimensionality of the sole of the foot, and has the effect of being comfortable to wear with fewer problems such as blisters.
