Abstract
A running shoe has an outer sole surface contoured uninterruptedly from a mid-sole landing zone to a relieved or negative heel at the rear and an upturned toe-off zone at the front to induce a rolling motion along the sole during the running stride. The shoe includes a shoe shell with a relatively incompressible outer sole structure and an internal suspension member compliant to the foot and formed of relatively compressible material formed to conform with the shoe shell. The method of manufacturing the shoe includes the steps of making a positive casting reflecting the weight bearing condition of the runner's foot or feet, and conforming the suspension member to the casting. The method also includes forming the outer shoe shells with curved outer soles and inserting the suspension members to complete the shoes.
