Abstract
Multiple shoe types are made from a plurality of generic molded base frames including a midsole and at least one upper portion integrally molded together. A first set of upper components is provided for forming a first shoe type secured to a first portion of the base frames and a second set of upper components is provided for forming a second shoe type secured to a second portion of the base frames. The upper portion that is integrally molded with the midsole may be a forefoot panel or a quarter. The various types formed from the generic frame include sneakers, backless shoes, slip-ons, skate shoes and boots. The generic unitary molded frame construction substantially reduces the cost of manufacture.
