Balanced and stable sole

Abstract

The invention provides a balanced and stable sole, comprising a middle sole and a big sole. The balanced and stable sole is characterized in that the front sole of the middle sole is in a fishbone-shaped structure which is provided with a backbone and lateral middle sole balanced strips, wherein the lateral middle sole balanced strips are correspondingly arranged at the inner and outer sides of the backbone respectively and distributed at intervals along the longitudinal direction; the backbone is positioned on the longitudinal center axis of the middle sole; a plurality of first grooves which penetrate through the upper surface and the lower surface of the middle sole and space the adjacent longitudinal middle sole balanced strips are formed between every two longitudinal middle sole balanced strips; the middle sole is made of a hard elastic soft material; the bending directions of the left side and the right side of each middle sole balanced strip are opposite; and supporting sheetsare arranged between the middle sole ranging from the front part of the sole to the middle part of heel and the big sole. According to the invention, the structures are adopted so that the sole has good flexural stability while effectively buffering and damping. In addition, the design of the wave-shaped middle sole balanced strips realizes the purpose of balanced conduction of inner-side pressure and outer-side pressure to further take the effects of balancing and stabilizing.

Description

technical field [0001] The invention relates to a shoe sole, in particular to a balanced and stable shoe sole. Background technique [0002] With the improvement of living standards and the advancement of science and technology, the comfort of shoe soles and its impact on health have gradually attracted people's attention. Therefore, at present, functional designs such as cushioning and shock absorption, air permeability, and deformation stability of the sole emerge in an endless stream. [0003] The Chinese Utility Model Patent No. 201020243647.4 discloses a high-elastic and lightweight sports shoe sole. By setting grooves on the forefoot and / or heel of the midsole and filling shock-absorbing materials and / or air cushions, the impact force is attenuated. . Regardless of whether it is filled with shock-absorbing materials or air cushions, and where the grooves are distributed on the sole, due to the need for separate special processing and installation on the sole, the pro...

AI Technical Summary

Problems solved by technology

Regardless of whether it is filled with shock-absorbing materials or air cushions, and where the grooves are distributed on the sole, due to the need for separate special processing and installation on the sole, the production cost is high; at the same time, due to the material differences between the filler and other parts of the sole, the The contact with the sole will produce a foreign body sensation on the sensitive sole, making the sole feel uncomfortable; moreover, the impact force on the sole during exercise is often distributed continuously according to the strength of the curved surface, so the cushioning design cannot only be concentrated on the forefoot and heel etc.
