Abstract: A shoe of California construction having an upper with a sock liner, an outsole, and a midsole between the sock liner and the outsole. The midsole comprises a molded polyurethane element having a lower surface of a contour complementary to the contour of the upper surface of the outsole and having an upper surface of a contour complementary to the shape of the bottom of a wearer's foot. A fiberboard backing sheet is bonded to the lower surface of the midsole. A leather wrap extends between the upper and the outsole and surrounds the side wall, the midsole, following the contoured shape of the midsole side wall.
