Abstract
A plurality of orthotic systems are provided. One bi-layer system is constructed from a single sheet of fabric that is molded into two layers. One tri-layer system includes a base layer; a mid-layer, and an upper layer. The upper layer is joined to the mid-layer and the mid-layer is joined to the base layer. The coupling of the base layer, the mid-layer and the upper layer create a rear spring section, a mid-spring section and a front spring section in which the upper layer is suspended over the mid-layer and the heel portion is suspended on the proximal heel end of the base layer.
Claims19
A tri-layer orthotic system comprising:
- a base layer having a distal toe end and a proximal heel end;
- a mid-layer having a distal toe portion, a mid-portion and a proximal heel portion, the distal toe portion of the mid-layer operably coupled to the distal toe end of the base layer to form a forefoot portion;
- and
- an upper layer having a front upper layer portion, an arch upper layer portion and a heel upper layer portion, the heel upper layer portion operably coupled to the proximal heel portion of the mid-layer to form a heel portion,
- wherein the operable coupling of the distal toe portion of the mid-layer to the distal toe end of the base layer and the heel upper layer portion to the proximal heel portion of the mid-layer is configured such that the upper layer is suspended over the mid-layer and the heel portion is suspended over the proximal heel end of the base layer to create a rear spring section, a mid-spring section and a front spring section.
