ABSTRACT:
A midsole (10 and 32) for heeled shoe (12) comprises a removable insert (10), a peripheral heel member (26) and a peripheral midsole member (32). The peripheral heel member (26) is joined to a portion of the perimeter of an upper surface (20) of an outsole (14) and peripheral midsole member (32) is joined to the remaining portion of upper surface (20) of outsole (14) and to an upper leveling surface (30) of heel member (26) to form a stepped orifice (38). A reinforcing layer (40) substantially less thick than the peripheral members (26 and 32) is joined to the outsole upper surface (20) within the orifice (38). A plurality of independent cushioning elements (46, 48 and 50) depend from a base member (44) of insert (10), and are sized in order to conform to the stepped orifice (38).
