Definitions

Abstract
An insole for footwear, of the type which is intended to be interposed, inside the footwear, between the user's foot and the sole, comprises an insole body (4) having a first surface (2) and a second surface (3) which are arranged opposite one another and, in use, face the user's foot and the sole, respectively, at least one of the surfaces being provided with a plurality of resiliently deformable appendages (6, 7, 8). The appendages are formed on the second surface (3) and have a shape with an intermediate portion (9) which is narrower than the outermost portion (10).
Description
- The present invention relates to an insole for footwear of the type which is intended to be interposed, inside the footwear, between the sole of the user's foot and the facing surface of the footwear sole, with an insole body having a first surface which faces the user's foot in use and an opposite, second surface which faces the footwear sole, at least one of the surfaces being provided with a plurality of resiliently deformable appendages.
- Insoles including these features are known, for example, from
US5,400526 ,W02007/064176 , fromDE10314606 , and yet others. - Most typically, these insoles have a plurality of appendages which are distributed variously over the first surface and are directed towards the user's foot. These appendages lead to a distribution of the plantar load, improving the comfort of the footwear and sometimes facilitating sports usage thereof.
- The invention proposes to modify the known insoles, providing improved foot support.
- In one embodiment of the invention, an insole is proposed which can offer a load-carrying capacity that is differentiated according to localized plantar loads.
- The characteristics and the advantages of the invention will become clearer from the detailed description of a preferred but not exclusive embodiment thereof which is described by way of non-limiting example with reference to the appended drawings, in which:
-
Figure 1 is a side view of an insole for footwear according to the present invention, -
Figure 2 is a plan view of the insole ofFigure 1 , from above, and -
Figures 3 and 4 are two different plan views of the insole ofFigure 1 , from below. - An insole formed in accordance with the present invention is generally indicated 1 in the drawings. The insole 1 is of the type which is intended to be interposed, in use, between the user's foot and the sole of the footwear, inside the footwear. The insole 1 is preferably formed by moulding with materials of the class known as thermoplastic polyurethane elastomers (TPU) and comprises a body 4 which is tapered from a heel region towards a toe region and in which two
opposed surfaces 2, 3 are defined. The first surface 2 faces inwardly relative to the footwear, is substantially smooth, and serves as a support for the user's foot whereas thesecond surface 3 bears a plurality ofappendages 6, 7 and 8 of substantially identical shape which are circular in plan, and are preferably formed with mixtures of different densities. Appendages of identical shape but having different resiliences and hence different load-carrying capacities can thus be provided in the various regions of the sole. The appendages 6-8 are arranged on thesurface 3 of the body 4 with a matrix-like distribution, being aligned in approximately parallel rows all arranged transversely and preferably perpendicularly with respect to the longitudinal toe-heel line of the insole 1. In a preferred version, the different mixtures are made evident by different colours of the appendages which are shown, by way of example, in a red colour for the mixture of greatest density (maximum load-carrying capacity), orange for the medium-density mixture, and grey for the softest and least dense mixture. All three mixtures are co-moulded simultaneously in a single mould. - All of the
appendages 6, 7, 8 have a substantially hourglass-like shape with an intermediate region 9 which has a cross-section that is both narrower than anoutermost region 10, remote from the body 4, and narrower than aroot 11 by which the appendage is attached to the body 4. - The appendages have a waisted region in the intermediate portion with a radial junction both towards the outermost portion and towards the root.
- The body 4 also has a plurality of through
ventilation holes 11 in one ormore regions 10 so that the compression of the insole during walking leads to a variation in the volume of the space underlying the second surface 3 (between the insole body and the footwear sole) as a result of the compression of theappendages 6, 7, 8, and a consequent forced circulation of air through theholes 11. - The insole of the invention thus achieves the results discussed above with the addition of many advantages which are connected mainly with improved walking comfort, differentiated load-carrying capacity, the ability to adapt automatically to the user's morphology, and improved foot ventilation.
