Problems solved by technology
[0002] Sports shoes due to their special purpose and consumer experience needs, in order to meet the rebound requirements, the material hardness is generally high and the density is relatively high. At the same time, due to the single material used in the formula and the irrationality of the formula, sports shoes The weather resistance is relatively poor, and the deformation after compression is high. The foam material of the sole is easy to deform after wearing for a long time, and the wearing experience and appearance will be greatly affected.
To reduce the density of sports shoes materials, if the existing formula is used, the performance of rebound and compression resistance will also decrease significantly.
