Abstract (en)
[origin: WO2009054626A2] Disclosed herein is a shoe including a midsole having a dual insert structure, the midsole including: a hard nylon injection piece layer; a low-hardness polyurethane layer covering the nylon injection piece layer; and a middle-hardness polyurethane layer covering the low-hardness polyurethane layer. The shoe is advantageous in that, since a midsole includes two different polyurethane layers, that is, a polyurethane layer having low hardness and a polyurethane layer having middle hardness, the midsole can completely absorb the impact transferred from the ground when it comes into contact with the ground, and thus the impact is not transferred to an ankle or knee joint. Further, the shoe according to the present invention is advantageous in that, since the midsole is formed by joining low-hardness polyurethane and middle -hardness polyurethane together without using an additional adhesive, the shoe is not hydrolyzed, thereby increasing the lifespan of the shoe.
