Description

A kind of sole shock absorber and sole

technical field

The invention relates to the field of footwear articles, in particular to a sole shock absorbing member and a sole.

Background technique

Shoes have become a necessity in people's daily life. In order to make the soles more comfortable in different motion states of the human body, a sole shock-absorbing member made of non-Newtonian fluid materials is usually added to the soles. According to the characteristics of non-Newtonian fluid materials, the speed of the force frequency affects its condensation state. When the human body walks slowly, the frequency of the impact force on the sole shock-absorbing member of the sole is slower, and the sole is softer and more comfortable; when the human body runs, the sole of the sole is more comfortable. The frequency of shock absorption is faster, the sole is stiffer, and the support performance is better.

Existing use of non-Newtonian fluid material to make the sole shock absorber, the non-Newtonian fluid material is usually foamed, and the shock absorption effect of the non-Newtonian fluid material after the foaming treatment is not as good as that of the liquid non-Newtonian fluid material; therefore, in order to In order to make the shock-absorbing effect of the shock-absorbing part of the sole better, it is necessary to study how to directly apply the liquid non-Newtonian fluid material to the shock-absorbing part of the sole of the shoe.
