Abstract
An improved expandable shoe and inner assembly are disclosed. The expandable shoe includes an outer shell and an adjustable inner assembly is disposed within the outer shell. The inner assembly has a first board portion and a second board portion in overlapping engagement with each other and a control to adjust the position of the first board portion relative to the second board portion. A lighted visualization window provides a visualization window to the inner assembly. The inner assembly may include size markings through the visualization window so that a size of the adjusted shoe may be determined as shoe size is adjusted.
