Abstract
A torsion-resistant three-density high rigidity midsole includes a midsole body having a front region, a back region, and a middle region integrally connected between the front and back regions. The front region has a front region density and a front region length. The back region has a back region length, and a back region density smaller than the front region density. The middle region has a middle region length, and a middle region density greater than the front region density. A sum of the front and middle region lengths is greater than the back region length. A cushion body is integrally formed on a top surface of the midsole body, and covers the front, middle and back regions. An elastic piece is sandwiched between the top surface of the midsole body and a bottom surface of the cushion body at a position corresponding to the middle region.
