Example Embodiment

[0013] The design inspiration of the present invention comes from spider webs. According to the research and experiments of scientists, a rope composed of spider silk is stronger and stronger than stainless steel bars of the same thickness. It can bear 5 times more weight than steel bars without being broken. Spider silk is very elastic. A spider silk with a diameter of only one ten thousandth of a millimeter can stretch more than twice before breaking. The main component of the spider web is protein, which is linked by polypeptides in a chain shape and is resilient. In life, we often find a small insect hitting the spider web and struggling desperately to deform the spider web, but it cannot collide the spider web. Broken, because the spider web can disperse the force generated by the movement during the deformation process. According to the structural characteristics of spider webs, laboratory researchers selected a variety of tough fibers to form spider webs and embedded th...

Abstract

The invention relates to a sole, in particular to an insole structure of sneakers. The insole structure comprises an insole made of an EVA or a polyurethane material and net cloth embedded into the underside and the side of the insole; the net cloth and the EVA insole are integrally foamed and molded; and the EVA insole protrudes from grids of the net cloth to form a plurality of protrusions. The insole structure uses a cobweb structure for reference, adopts advanced EVA foaming technology and once molding of the net cloth and forms one layer of the cobweb structure by embedding the net cloth in the underside and the side of the insole in the EVA raw material foaming and molding process to improve and increase the tearing resistance, wearing resistance and tensile resistance of the insole, also improve the stability of the insole on the heel motion, have three-dimensional shape effect at the same time, and close to and realize partial functions of the double-density insole.

Description

technical field [0001] The invention relates to a shoe sole, in particular to a sports shoe midsole structure. Background technique [0002] The role of the midsole structure of sports shoes is to provide cushioning, stability and flexibility, and it is one of the most important parts of sports shoes. At present, the midsole of sports shoes is generally made of EVA or polyurethane foam, and different sports performances can be realized by controlling the raw material formula, temperature during production, and molding time. At present, one of the cutting-edge technologies of midsole is to design and manufacture it with double density according to human body sports biomechanics and sports anatomy. It is difficult to make midsole, and it is difficult to find sports shoes with double-density midsole in the domestic market. Therefore, the comprehensive performance of the midsole structure of ordinary sports shoes is not high. Contents of the invention [0003] The technical ...
