Patent number: 7581337Abstract: 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.Type: GrantFiled: June 24, 2004Date of Patent: September 1, 2009Assignee: Inchworm, Inc.Inventors: Harry Miller, Byong M.

Patent number: 6817116Abstract: 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. A visualization window provides a view port to the inner assembly so that size markings on the inner assembly may be visible through the view port. The inner assembly includes first and second board portions, each shaped for relative movement with respect to the other, and a manually urgable member. When the urgable member is released from an engagement member fixed to one of the first and second board portions, the first and second board portions may be moved to adjust the shoe dimension and when the urgable member is in engagement with the fixed engagement member the first and second board portions resist movement relative to one another.Type: GrantFiled: July 9, 2002Date of Patent: November 16, 2004Assignee: Inchworm, Inc.Inventors: Kwon Dong Chil, Harry Miller
