Shoe having a spinal disk material damping element

Abstract

A shoe such as a pump, high heel shoe, or stiletto, has an insole and a heel. In the heel, the insole and / or the ball region, at least one damping element is integrated. The damping element has a Shore D hardness in the range of 28-33, a modulus of elasticity in the range of 28-38 MPa, and a tensile stress of 9-11 at 600% elongation. In this way, a shoe is realized that is elegantly fashioned and can be provided with a high-quality design without having to compromise on comfort and convenience.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This continuation application claims priority to PCT / EP2016 / 054558 filed on Mar. 3, 2016 which has published as WO 2016 / 146397 A1 and also the German application number 10 2015 204 927.2 filed on Mar. 19, 2015, the entire contents of which are fully incorporated herein with these references.FIELD OF THE INVENTION[0002]The invention relates to a shoe, in particular a pump, high-heel shoe or stiletto, having an insole and a heel, wherein a damping element is integrated in the heel and / or in the insole, in particular in the region of the heel and / or the ball of the foot.BACKGROUND OF THE INVENTION[0003]A shoe having rubber elements arranged in the insole is known from US 2007 / 0151124 A1.[0004]Damping soles are used in particular in sports shoes in order to damp the forces which act on the body when running and jumping. Since sports shoes can have very thick soles, correspondingly large quantities of different damping materials can be used.[0...

AI Technical Summary

Benefits of technology

The patent describes a shoe with a special damping element that can relieve pressure on the foot joints, knee joints, and spine. This element is hard and absorbs a lot of energy, making it effective in high-heeled shoes. Its mechanical properties are similar to those of intervertebral disc implants. The damping element is integrated into the insole or an optional cover, providing comfort and flexibility while wearing the shoes. This biomechanical approach reduces the impact of force on specific locations in the foot and is useful for people who have pain or deformation in their feet. The shoe also allows for longer periods of comfortable high-heel walking.

Problems solved by technology

Particularly with elegant ladies' shoes (high heels), however, this is not possible since the design does not permit the use of large quantities of damping material.

In addition, feet and joints are subjected to different loads when walking in high heels from those when jogging or walking.

Ladies who like to wear high heels therefore have to live with side-effects such as pain in the front foot (“burning of the balls of the feet”), blisters, swollen feet, up to long-term damage for the joints and back.

However, this impairs the fit of the shoe in most cases.

Current gel inlays are in most cases silicon inlays whose damping properties are, however, rather low or not present.

However, this results in the inserts being able to be perceived as foreign bodies which is haptically generally perceived to be unnatural and disruptive, in particular during walking.
