Human locomotion assisting shoe
View Patent ↗Embodiments of footwear, in particular, a shoe, sandal or boot, may reduce the effort and improve the performance of walking, running, hiking, marching, and various other gaits as well as jumping, hopping, and other motion involving the ankle and lower leg and Achilles tendon, through integration of force-carrying mechanisms within footwear that manage the forces and energy associated with such motion by productively harvesting and storing energy during dorsiflexion motion and releasing and returning energy during plantar flexion. One structural element of such footwear may comprise a top collar yoke having anterior and posterior gussets forming a channel and a shoe comprising a rotation zone supporting the channel and an elastomeric zone forming a tension spring via an elastomeric overlay or otherwise providing a spring-like member approximately parallel to and to assist the Achilles tendon during locomotion.
1. Footwear comprising
a rotatable top collar yoke capable of rotation relative to a remaining portion of a shoe, the rotatable top collar yoke comprising an anterior gusset and a posterior gusset, the anterior and posterior gussets forming a channel therebetween;
the shoe supported by an elastomeric overlay comprising first and second zones, the first and second zones comprising a rotation zone supporting the channel and an elastic zone defining a region of elastomeric activity and creating a tension spring.
2. The footwear according to claim 1 , the rotatable top collar yoke comprising X stitching in the vicinity of the channel.
3. The footwear according to claim 1 , the elastomeric overlay being bonded at reduced zones of bonding agent at a superior and inferior elastic anchor zone.
4. The footwear according to claim 1 , the elastomeric overlay being anchored at a rear of the footwear to a heel portion of the shoe.
5. The footwear according to claim 1 further comprising yoke eyelets of the elastomeric overlay for selectively adjusting the elastomeric overlay by adjustably lacing the yoke eyelets.
