Abstract
A midsole (10 and 22) for an activewear shoe (12) comprises a removable insert (10) and a peripheral member (22). The peripheral member (22) is joined to the perimeter of an upper surface (18) of an outsole (14) to form a receptable (28). A reinforcing layer (31) substantially less thick than the peripheral member (22) is joined to the outsole upper surface (18) within the receptable (28). A plurality of independent cushioning elements (34) depend from a base member (32) of insert (10), and are sized in order to conform to the lift of peripheral member (22). The cushionability and resiliency of insert (10) may be selected according to the wearer's weight and cushionability preference.
