A barefoot orthotic is a foot support that adheres to the underside of a user's foot and is placed so that it extends longitudinally between the metatarsal head region and the calcaneal plantar tuberosity, and laterally between the lateral midfoot and the medial arch. By using a silicone polymer or other similar material, a barefoot orthotic can self-adhere to the skin of a user's foot. A barefoot orthotic can have a midfoot strike zone surrounding the forward portion of the calcaneal plantar tuberosity, a navicular support, a medial arch support, a forefoot propulsion pad, a lateral forefoot support, a lateral midfoot support, a cuboid support flange, a lateral heel support, and a balance rail extending longitudinally from the midfoot strike zone to the forefoot propulsion pad. Together, these components work to support and align the foot and thereby alleviate symptoms of various foot and leg conditions.
