  • Patent number: 4461288
    Abstract: A stabilizing strap (25) for exterior use with a shoe (28) including a dorsal strap (26), an Achilles strap (30) and a plantar strap (32). One end of the dorsal strap (26), the Achilles strap (30) and the plantar strap (32) are connected together at a point (34) on the medial side of the foot.
