Abstract
A foot orthotic designed to unweight the ball of the foot, or more precisely the foot region of one or more of the five metatarsal heads, to alleviate pain while walking or standing. Using a connector from the foot orthotic to a sulcus bar provides a reproduceable front to back position of the sulcus bar relative to the foot orthotic. In certain aspects of the invention the connector provides further unweighting of the metatarsal heads, and also ensures a specific custom position of the sulcus bar throughout the foot orthotic fabrication process. Various methods of manufacturing an orthotic are also disclosed.

An orthosis for a patient's foot comprising:
- a body portion having a top side and a bottom side, a heel portion, a midfoot portion coupled to and extending distally from the heel portion, and a forefoot portion, coupled to and extending distally from the midfoot portion, the forefoot portion terminating in distal edge distal to the midfoot portion;
- at least one sulcus bar connector having an elongated body with a first end zone coupled to the distal edge, and a second end zone extending distally therefrom, the sulcus bar connector being disposed to operationally lie inbetween any two adjacent metatarsal heads of a patient's foot;
- a sulcus support bar coupled to the second end zone and laterally extending upwardly and laterally therefrom;
- the orthosis dimensioned to operationally fit under the patient's foot wherein the heel zone or a portion thereof underlies the foot calcaneus, the midfoot zone or a portion thereof underlies the foot arch, the distal edge or a portion thereof underlies an area proximal to the metatarsal heads, and the sulcus bar or a portion thereof laterally underlie at least a portion of the foot sulcus corresponding to at least one proximal phalanx of the foot or a lateral portion thereof.
