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. The inner assembly includes a first sole portion, a second sole portion, and a manually urgable member. The manually urgable member has at least a portion of the member accessible from the outer shell, and in engageable and releasable communication with an engagement member, fixed to one of the first and second sole portions. When the urgable member is released from the fixed engagement member the first and second sole portions may be moved to adjust the dimension of the shoe and when the urgable member is in engagement with the fixed engagement member the first and second portions resist slidable movement relative to one another.
