Expandable shoe and shoe assemblies |
摘要 |
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. The control includes a locking mechanism shaped to engage and hold one of the first and second board portions, a biasing mechanism to bias the locking mechanism into engagement with one of the first and second board portions; and an urging member having a proximal portion external of the shoe outer shell and positioned and movable transversely to a longitudinal direction of the shoe and in transverse alignment with the locking mechanism. In one embodiment, 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.
