Abstract
Abstract A shoe construction comprising a unitary, molded sole unit having a plurality of female connectors spaced along the periphery of the upper portion thereof, and an upper and an insole permanently or removably attached to the sole unit to form a finished shoe. In one embodiment, male connectors are secured to the peripheral portion of the insole and are positioned to mate with the female connectors in the upper portion of the sole unit. The edge portions of the upper are turned in under the insole and are provided with a plurality of holes which are positioned to enable the male connectors on the insole to extend therethrough. In this manner, the upper and the insole can be removably or permanently attached to the sole unit. In another embodiment, the male connectors are secured to the turned-in edge portions of the upper, and additional male connectors are secured to the insole for the purpose of removably or permanently securing the insole and the upper to the sole unit.
