1. A tri-layer orthotic system having a heel portion and a forefoot portion, the 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 coupled to the distal toe end of the base layer to form the forefoot portion of the tri-layer orthotic system; 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 coupled to the proximal heel portion of the mid-layer to form the heel portion of the tri-layer orthotic system,
wherein the 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,
wherein the heel portion of the tri-layer orthotic system and the forefoot portion of the tri-layer orthotic system are configured to support respective heel and forefoot portions of a foot through at least a portion of a gait cycle.
