Footwear sole

Abstract

Shoe insert (1) comprised of numerous elements that provide shock absorption, elements that are made up of numerous cavities (2), each corresponding with pivots or shock absorbing (3) elements, which extend out from the bottom part of the insert; shock absorption elements (2, 3) configured in such way that, when compressed by the user's weight, they compress and absorb the shock that is produced by the stepping action, thus achieving a sensation of well being and comfort.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of International Application No. PCT / ES2009 / 070308, filed Jul. 23, 2009, which claims priority to Spanish Patent Application No. P 200930119, filed May 4, 2009, the disclosure of the prior application is incorporated in its entirety by reference.[0002]The objective of this invention is a shoe insert comprised of multiple shock absorbers for the foot while achieving a sensation of well being and comfort.PRIOR STATE OF THE ART[0003]Presently there are different types of shoe insoles that exist with shock absorption properties, which are generally based on the insertion of a spring or other similar shock absorption element into the shoe insole. However, these solutions are technically complicated because they require complicated manufacturing processes.[0004]Among the shock absorption inserts we have the PCT WO9947014 which describes an insert with multiple support elements that provide shock absorption in ...

AI Technical Summary

Benefits of technology

[0006]In the spaces that make up the inside part of the shock absorbing elements or pivots, a base has been inserted which does not completely fill in the shock absorbing area because this way, when weight is added, the outer ring of the space gives in until it is supported on to the inner base or pivot, which provides a second and harder shock absorption and at the same time, assists in returning the shock absorbers to their initial position when the weight of the foot ceases to press on them thus preventing any loss of efficiency with usage and from walking.

[0007]These inner pivots will adapt to each point on the foot they are in contact with and in accordance with the weight they are supporting at that time, forming a type of regulated support at the bottom of the foot in accordance with the amount of surface contact area and weight it supports at each point.

[0008]As an advantage, the described shock absorbing insert also has the ability to circulate air from the heel to the foot sole, as in the natural way of walking. This double effect of the shock absorption and ventilation is produced by the same mechanism that creates the shock absorption pivots; in other words, by their compression. This way, when they are compressed, the air is forced out through these cavities, circulating through the channels that inter-connect the shock absorbers, and producing an air flow that provides a necessary sensation of comfort throughout the length and width of the bottom of the sole.
