Abstract
Abstract A shoe construction includes a shoe body which is conventional except that it does not include a shoe sole, a first layer of material fixed to the undersurface of the shoe body, a second layer of material for attaching to and detaching from the first layer of material, and a shoe sole fixed to the second layer of material. The first and second layers of material include means such as velcro for enabling attachment and detachment of the two layers. With this construction, when a shoe sole becomes worn, it can be detached from the shoe body and replaced by a new shoe sole.
