Abstract
Methods and apparatus for securing a replaceable inner sole to an open toe/open heel shoe are provided. Flaps are provided at the toe and heel portions of the unit bottom of the shoe. The replaceable inner sole is positioned within slots formed by the flaps. The flaps may extend around the front and rear of the shoe to prevent forward and rearward slippage, and may extend along the sides of the shoe to prevent lateral slippage. The flaps may be tapered to help eliminate irritation of the wearer's foot. A specially contoured last for pressing the sole of a shoe having toe and heel flaps is also provided.
