Abstract
An expandable shoe includes an outer shell and an adjustable inner assembly disposed within the outer shell. The inner assembly has a control to adjust a dimension of the inner assembly and thereby a corresponding dimension of the shoe. A visualization window provides a view port to the inner assembly so that size markings on the inner assembly may be visible through the view port. The inner assembly includes first and second board portions, each shaped for relative movement with respect to the other, and a manually urgable member. When the urgable member is released from an engagement member fixed to one of the first and second board portions, the first and second board portions may be moved to adjust the shoe dimension and when the urgable member is in engagement with the fixed engagement member the first and second board portions resist movement relative to one another.
