Abstract
Disclosed herein is a dynamically interactive combination of a shoe and an externally adjustable internal orthotic foot cradle formed of a fabric strap material. The disclosed combination attenuates and beneficially disperses the deforming forces experienced by the foot in weight bearing, limits the extent of pronation and excursions of the various joints of the mid and hind foot during weight bearing and the cradle can store mechanical energy absorbed during weight bearing and return at least a portion of such stored energy in the form of restorative forces applied to the mid and hind foot during the non-weight bearing phase of the gait cycle.
Claims18
A shoe equipped with an internal orthotic cradle device and comprising:
- (A) a shoe having a sole and a foot-enclosing upper affixed thereto, said upper having lateral and medial sides and a longitudinal center line and being adapted to enclose at least one of the mid foot and hind foot of a wearer, said upper having a strap-receiving aperture therethrough in at least approximate correspondence with each of the following anatomical loci of a foot received therein:
- (i) proximal and superior to the lateral aspect of the calcaneal-cuboid joint, (ii) dorsomedial aspect of the medial longitudinal arch, and (iii) medial aspect of the calcaneous inferior to the medial malleolous;
- (B) a generally Y-shaped orthotic cradle composed of strap members disposed within said upper, said cradle comprising a base leg member defining a plantar-lateral heel engagement strap, an anterior arm member defining a medial longitudinal arch engagement strap and a posterior arm member defining a plantar-medial heel engagement strap;
- said base leg member comprising a relatively wide plantar support portion having a medial end and a relatively narrower lateral free end portion, said relatively wide plantar support portion being disposed obliquely transverse across the floor of the shoe and said lateral free end portion passing upwardly along the inside of the lateral side of the upper and slidingly passing to the exterior thereof through said aperture of (A)(i), and means to secure that section of said free end portion exterior of said aperture of (A)(i) to the lateral side of said upper at a location spaced posteriorly of said aperture and to thereby engage the lateral heel;
- said anterior arm member having one end thereof secured at an anterior angle to the medial end of said relatively wider plantar support portion of said base leg member and passing therefrom upwardly and forwardly along the inside of the medial side of the upper and slidingly passing to the exterior thereof through said aperture of (A)(ii), that section of said anterior arm member exterior of said aperture being adapted to be disposed laterally over the medial longitudinal arch of the foot, and means to adjustably secure the free end thereof to the upper at a location sufficiently lateral of said aperture of (A)(ii) as to capture the apex of the medial longitudinal arch of the foot thereunder and to thereby engage the medial longitudinal arch;
- said posterior arm member having one end thereof secured at a posterior angle to the medial end of said relatively wider plantar support portion of said base leg strap member and passing therefrom posteriorly and upwardly along the inside of the medial side of the upper and slidingly passing to the exterior of the upper through said aperture of (A)(iii), and means to adjustably secure the free end of that section of said posterior arm member exterior of said aperture of (A)(iii) to the medial side of said upper at a location spaced posteriorly of said aperture and to thereby engage the medial heel.
