INSOLE FOR A HIGH-HEELED SHOE

Abstract

The present insole for a high-heeled shoe has reduced friction in the direction of a contact force from toe to heel and increased friction in the direction of a contact force from heel to toe. The insole is made of a flexible material and has disposed thereon a plurality of protruding elements, which are inclined from toe to heel. The protruding elements can be in the form of: filaments, bristles, burrs, scales, serrations, ribs, etc.

Claims

1. An insole for a high heel footwear, the insole being made of a flexible material on which a plurality of protruding elements are arranged, characterized in that the protruding elements are inclined in a direction from a toe to a heel in such a way that vertices of the protruding elements are displaced in a direction from the toe to the heel relative to a middle of bases of the protruding elements.

2. The insole according to claim 1, characterized in that there are grooves on a heel side in front of the protruding elements in the insole.

3. The insole according to claim 1, characterized in that the protruding elements are made of villi, bristles, thorns, scales, denticles, scars.

Description

SUMMARY

[0009] The insoles different coefficient of friction depending on the direction of contact effort can solve a problem.

[0010] The insoles which has the lowered friction in the direction of contact effort from a sock to a heel and the increased friction in the direction of contact effort from a heel to a sock is offered. On the flexible insole supplied with fasteners to the top part of a sole the great number of elements' appendages inclined from a toe to a heel are placed. The appendages can be executed as a: fibers, bristles, thorns, scales, cloves, scars, etc. At the effort direction from a toe to a heel, for example at instep, in passing inclined appendages are turned in by foot even stronger and don't show resistance to movement, and foot is freely displaced to a footwear back. When the person goes by foot, the minimum foot movement from back to a toe on an inclined sole lifts the appendages (against the grain) which assume loading, create the increased friction, and interfere with rolling foot to a toe. During passing the appendages will constantly displace foot to a footwear back, thus a part of loading will be distributed on all foot and load of a toe-toe-cap-fasciculate part of foot will be lowered. According to the user's leg at more uniform distribution of loading will be tired less and the probability to receive foot deformations because of carrying a heel will decrease.

[0011] The insoles can be made by formation of elastic polymers such as: the plasticized PVC, polyurethane, latex. And it can also be made of textile material with inclined pile.

BRIEF DESCRIPTION OF THE DRAWINGS

[0012] On a FIG. 1 the insole 1 pasted on an inclined sole 2 is represented. Foot 3 at the time of a step applies pressure down, and at insignificant shift to a footwear toe lifts the lodges on the insole 1 which accept loading and interfere with foot rolling down. The movement is against the grain.

[0013] In FIG. 2, the foot 3 is shown at the time of lifting the leg. The protruding elements (ledges) on the insole 1, when the load is reduced, return to an inclined position, they bend even more strongly and do not resist the movement of the foot to the back of the shoe. Movement is with the grain.

[0014] FIG. 3. The ledges can be executed in various forms and have a different inclination. Tops of the ledges can be roundzone a, pointedzone b and c, multiplezone d. The inclination can be bigzone b, smallzone c. Each ledge has its height with the top and its basis. The ledge top inclination is in the direction from a toe to a heel, which means that the top of the ledge is displaced relative to the middle of the basis; the direction of the displacement is from in the direction from the toe to the heel.

[0015] FIG. 4. The ledges can be executed in various forms, for example:

in the form of scarszone a, in the form of scales or cloveszone b, in the form of thornszone c, in the form of the cloves supplied with inclined micro ledgeszone d.

[0016] FIG. 5. The insoles can be made of textile material with solid pile: not cutzone a, cutzone b. Pile can be made of thermoplastic monothread and inclined by mangling a certain direction.

[0017] FIG. 6. A fragment of an insole of an elastic polymer is shown in an enlarged view. In the base 1, from the side of the heel, in front of the protruding elements 5, depressions 4-zone L can be made. When lifting the foot of the foot, moving to the backside, it drowns the protruding elements 5 in the indentations 4zone a. The resistance of the insole to the movement of the foot to the back will be minimal. When the leg is lowered, the protruding elements will return to their normal positionthe zone L, and then they will rise, giving the maximum resistance to the rolling of the foot in the sockzone C.

[0018] he insoles fragment from the elastic polymer in an enlarged view is shown. In the basis 1 from a heel before the ledges 5 deepening's 4zone b can be made. At instep, the foot, moving to a back will drown the ledges 5 in deepening's 4zone. Insoles resistance to the foot movement to a back will be minimum. When lowering a leg the ledges will return to usual positionzone b, and further will rise, showing the maximum resistance to rolling foot to a toezone c.
