  • Publication number: 20050115113
    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.

  • Publication number: 20050055848
    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.
