Patent attributes
The convertible shoe with interchangeable sole consists of an upper to hold the foot and an interchangeable outsole. There is an attachment surface on the underside of the upper and an attachment surface on the topside of the outsole, and the two attachment surfaces are paired and configured to securely attach the two components while also being detachable to allow for the interchange of different outsoles having different tread surfaces. The attachment surfaces are a non-flat contoured shape. There are two protruding ridges on one surface, one substantially under the toe and the other under the heel and part of the arch. These mate with a recessed channel on the other surface. There is also attachment material on both surfaces that are mated and provide a secure attachment.
