EVA is a very common basketball shoe sole material,with light weight,strong shock absorption,moderate comfort and other advantages.In order to solve the problems of difficult degradation and poor environmental protection of ordinary EVA materials,a new type of plant fiber midsole basketball shoes was prepared using hemp stalk plant fiber and EVA material as matrix,and some of the lower limb biomechanical characteristic parameters were obtained when wearing the basketball shoes to simulate basketball jumping.The results show that compared with traditional basketball shoes,this kind of plant fiber midsole material has moderate quality,good shock absorption and better environmental protection,and can replace the traditional basketball shoe midsole material to a certain extent.
