Description

Technical Field

[0001] The invention relates to a shock-absorbing propulsion sole, belonging to the technical field of shoe materials. Background Art

[0002] Sports shoes, such as marathon running shoes, need to be light and have good support and rebound performance to reduce the burden of the shoes during long-term running. Lightweight and soft soles usually have relatively poor support and rebound performance, and it is difficult to form efficient propulsion through the rebound of the sole. For this reason, there is a type of shoe on the market that adds a propulsion support sheet to the midsole to enhance the support performance and rebound performance. The propulsion support sheet is made of a material with better support performance than the midsole, thereby compensating for the support performance and rebound performance of the sole, and can more efficiently assist the propulsion of the foot. However, the existing soles of this type still have the disadvantages of being relatively heavy and having relatively poor shock absorption performance.
