A preformed, flexible orthotic for disposition between a shoe and a foot of a user, the orthotic comprising:

• a medial wing configured to be disposed beneath a navicular bone of a foot of a user, wherein the medial wing is configured to be disposed along a medial side of the foot, and wherein the medial wing comprises an endpoint configured to be disposed beneath a medial edge of the medial side of the foot;
• wherein the orthotic defines a functional support structure which extends between a calcaneus of the foot and a metatarsal head area of the foot, wherein the functional support structure is configured to not extend under the calcaneus of the foot or under the metatarsal head area of the foot;
• a medial portion of the medial wing of the orthotic, wherein in response to the orthotic being placed in between a shoe and the foot, the medial portion is configured to be disposed along a medial wall of the shoe, wherein the medial portion is configured to not extend past a top portion of a midfoot of the foot;
• a lateral portion of the orthotic configured to be disposed along a lateral side of the foot, wherein the lateral portion is configured to not extend beyond the lateral side of the foot;
• wherein the orthotic varies in width and tapers to 0 mm along all edges, wherein a greatest vertical thickness of the orthotic, ranging between 6 mm and 10 mm, is at a medial midpoint, wherein the orthotic radially tapers from the medial midpoint to a thinner vertical thickness of the orthotic, ranging between 2 mm and 4.5 mm, along an outer edge of the lateral portion of the orthotic, wherein the orthotic tapers from a first thickness level ranging between 2 mm and 4 mm to 0 mm between a top of the medial wing to the endpoint, and wherein a ratio of a maximum length to a maximum width of the orthotic is approximately 1 to 0.78.
