Shock-proof sprain-preventing sole

Abstract

The invention provides a shock-proof sprain-preventing sole, which sequentially comprises an undersole, a mid-sole and an inner-sole from top to bottom, and is characterized in that: a sprain-preventing skeleton is also arranged between the mid-sole and the inner-sole, the sprain-preventing skeleton is made of a thermosplastic urethanes (TPU) material, and the sprain-preventing skeleton is at least arranged on a quarter part between a front half sole and a heel; and two sides of the sprain-preventing skeleton are respectively bent and extent to form a positioning sheet closely along corresponding surfaces of the mid-sole and the inner-sole, each positioning sheet is divided into an upper positioning sheet and a lower positioning sheet, the upper positioning sheets are bent and extent to two outer side walls of a quarter part of the inner-sole closely along two sides of the bottom surface of the quarter part of the inner-sole, and the lower positioning sheets are bent and extent to two outer side walls of a quarter part of the mid-sole closely along two sides of the upper surface of the quarter part of the mid-sole. The shock-proof sprain-preventing sole not only has an excellent shockproof function and can effectively absorb and eliminate an impact force of the feet from the ground, but also can be automatically restored, so the over-deformation of the sole can be prevented, the sprain of the feet can be avoided, and the balance and movement stability of the human body can be maintained.

Description

technical field [0001] The invention belongs to the field of shoemaking, in particular to a shock-absorbing and anti-sprain sole. Background technique [0002] Along with the raising of people's living standard, people also more and more higher to the performance requirement of shoes. Shoes, as people's daily necessities, have the functions of keeping warm and dispelling cold, bearing friction and impact, anti-skid and shock absorption, thereby protecting human feet. The shoe is mainly composed of the upper and the sole. Whether the shoe is comfortable or not depends first on the sole. The sole is the part of the shoe that is in direct contact with the ground. It is directly subject to the friction and impact of the ground, and at the same time transmits the reaction force of the ground to the foot. The sole includes the insole, midsole and outsole from top to bottom. For some shoes, especially for sports shoes, people hope that the feet can be effectively protected during...

AI Technical Summary

Problems solved by technology

For example, the shock absorption design of common soles is a fully enclosed shock-absorbing airbag based on aerodynamic principles. However, once the seal of the shock-absorbing airbag is damaged and the air leaks, the shock-absorbing effect will be lost, and the shock-absorbing airbag is thick and soft. When the sole transmits the ground impact force to the sole of the foot, the shock-absorbing airbag is easy to be skewed and cannot be corrected, and the sole cannot be restored to its original shape to protect the foot from being sprained; there are also EVA high-elastic materials used to make the midsole, and its shock-absorbing effect only depends on The midsole itself has elasticity and acts as a shock absorber. Its shock absorber effect is not great, and it does not have anti-twist function.
