  • Patent number: 6128835
    Abstract: A self adjusting frame for footwear comprises a strap slideably passing through a plurality of connectors spaced apart and adjacent to the sole, the strap passing around the heel of the footwear and having its two ends connected to the footwear. Lacing crosses over the footwear upper, with the lacing slideably engaging the strap so that when the lacing is tightened the strap is likewise drawn tight. The lacing and strap combination thereby secures footwear to a foot about substantially the periphery of the foot, and further self adjusts to develop differently oriented foot securing force vectors for differently shaped feet. Footwear comprises lacing and a strap passing through a plurality of connectors spaced apart around a shoe, with the lacing slideably engaging the strap. As the lacing is tightened the strap is thereby drawn tight. The footwear is thus secured to a foot about substantially the periphery of the foot.
