Description

Damping breathable sole

Technical Field

The invention relates to a component of footwear, in particular to a damping and ventilating sole.

Background

The comfort of shoes, especially athletic shoes, involves a number of indicators including fit, cushioning, energy return, thermal wet comfort, support stability, pressure comfort, flex performance, weight reduction, etc., and among these, slip and cushioning are the primary properties under investigation. With the increasing consumer's standard of living and the increasing specialization of sports, how to enhance and balance the properties of soles has become a major concern for shoe design manufacturers. The damping and ventilation are 2 important indexes of the sole, most of the prior soles are made of whole block materials, the damping structure and the ventilation structure are respectively arranged, the damping and ventilation structure is fresh, and the damping and ventilation performances of the sole are difficult to be considered.

The Chinese patent application number 201210407997.3 discloses a sole with excellent elasticity and super-strong ventilation function, which comprises an outsole and a midsole connected with the outsole and formed by interweaving and pressing elastic threads. The sole has novel structural design and excellent elasticity and super-strong ventilation function. When the shoe is manufactured and used, a certain gap is reserved between the elastic threads, so that ventilation and ventilation can be realized, sweat generated by the extrusion contact between the bottom of the sole and the top surface of the sole can be directly emitted from the sole, and the ventilation effect is good; the midsole formed by interweaving elastic threads randomly has excellent elasticity and good shock absorption effect on the whole sole, and is particularly suitable for being worn by a user during leisure or sports. However, this solution has the following disadvantages: firstly, due to the fact that the elasticity of the silk threads is small and the elastic silk threads are hardened after interweaving and pressing, the shock absorption performance of the midsole is further affected; secondly, the midsole of the scheme performs air exhaust and suction by means of gaps and deformation, has low air exchange efficiency, and cannot perform drainage and air exhaust well in the professional sports field, the Xixi shoe field and the like; third, because consumers are diversified, such as weight difference, running posture, running distance and the like, the varus degree or valgus degree of the feet of each person is inconsistent, and the supporting performance requirements of the shoes are also different, the scheme obviously has difficulty in effectively meeting the personalized and dynamic change requirements.
