Footwear With Removable Midsole And Outsole

An article of footwear comprising:

• an outsole having a lower surface, an upper surface, and a gasket extending upward from the upper surface, the gasket having an upwardly protruding forefoot gasket extension and heel gasket extension, each of the forefoot gasket extension and the heel gasket extension spaced above the upper surface to form respective channels, the outsole having an area between the forefoot gasket extension and the heel gasket extension that includes pair of protrusions extending upward from the upper surface;
• an upper having an open area defined by a lower edge and a lateral band, the lower edge having a perimeter rand extending into the open area, the lateral band dividing the open area into two open areas that respectively correspond to locations of the forefoot gasket extension and the heel gasket extension of the outsole, the lateral band being split into a lateral tab and a medial tab, the lateral band having at least one retention slot positioned to engage the pair of protrusions of the outsole, and the perimeter rand shaped and positioned to releasably mate with the channels formed by each of the forefoot gasket extension and the heel gasket extension by inserting the perimeter rand into the channels of the outsole;
• and
• a midsole having an upper surface and a lower surface, the lower surface having at least a ledge extending about a perimeter of the midsole, the midsole configured to be received within the upper, the ledge configured to rest on the forefoot gasket extension and the heel gasket extension of the outsole when the midsole is received within the upper.
