  • Patent number: 7581337
    Abstract: An expandable shoe includes an outer shell and an adjustable inner assembly within the outer shell. The inner assembly includes a first sole portion, a second sole portion, and a screw drive. The screw drive has a screw passing through a screw insert mounted to one of the first and second sole portions and a screw-receiving portion attached to the other of the first and second sole portions, so that turning the screw causes the sole portions to move relative to one another, thereby adjusting a dimension of the shoe. The shoe includes a manually operable control to turn the screw without the need for tools. The control is operable between a first position in which the control resists movement around an axis defined by the screw and a second position in which the control can be used to turn the screw to adjust a dimension of the footwear.

  • Patent number: 7287294
    Abstract: A method of making an expandable shoe is disclosed. An intermediate footwear structure is provided having an expandable upper portion. A stabilizing material is provided to the intermediate structure to resist expansion of the upper portion, and a last is inserted into the intermediate structure. A subsequent manufacturing operation is performed to the intermediate structure, and the stabilizing material is acted upon to permit longitudinal movement of the upper portion. The size of the last is selected from among the sizes within the intended range of shoe sizes for the expandable shoe, depending on the characteristics of the upper portion of the shoe, and the desired shoe size range.

  • Patent number: 7137212
    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. One of the board portions has a longitudinal projection which extends into a corresponding cavity in the sole of the shoe.

  • Patent number: 7080468
    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.

  • Patent number: 6883254
    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. 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.
