An article of footwear includes an upper attached to a stabilizer, an outsole, a first pod, and a second pod. The stabilizer has a lower surface and a first securing mechanism. The outsole has a first retention mechanism and an interior surface. The first securing mechanism is retained by the first retention mechanism. A volume between the lower surface and the interior surface forms a midsole cavity. The midsole cavity receives the first pod and the second pod.

A peg insole including an integrally molded unitary foam body covered. The foam body may be covered with a cover layer, such as a stretchable fabric, on a top surface of the foam body opposite the pegs. The foam body is includes a base layer with a plurality of pegs protruding therefrom. The foam body may include a contoured shaped to comfortably fit a patient's foot including, for example, a medial support portion, a lateral support portion, and a heel cup. The peg insole may be used, for example, in a medical shoe. Also provided is a method for forming the peg insole.

A footwear kit, comprising: left and right items of footwear; left and right forefoot inserts receivable in the left and right footwear items, respectively, so as to tighten the fit thereof to a wearer; a fitting guide directing that, should the wearer have an orthotic for either or each foot, a said forefoot insert be arranged such that it underlies the orthotic in the footwear item for that foot if the fit of that footwear item with only the orthotic therein is loose.

A removable and adjustable insert for footwear has slots placed in the insole and/or midsole of the shoe to allow access to the arch and/or metatarsal and/or heel regions of the insole and/or midsole. In an embodiment, an insert placed into the arch insert slot that establishes how much the arch protrudes above the remainder of the top surface of the insole. One or more inserts are provided having different thicknesses so that the height of the arch can be varied by the user or at the direction of a third party, such as a doctor or a trainer.

AI driven motion tracking and alignment systems configured to generate time-normalized three dimensional (e.g. frontal, sagittal, transverse) data associated with pronation and/or supination of lower extremities of a user are described. A semi-rigid foot orthotic can have sensors embedded in flexible regions. Data from the sensors is used to measure how the orthotic bends to determine forces from a lower extremity of the user acting on the orthotic. Data on the flexing, bending, and/or rotating of portions of the orthotic (including velocities, accelerations) may be compared to analyze in shoe pronation and/or supination. Other detectors can measure the temperature, body weight, heart rate, and timing of motion. An adjustment device can be used to adjust the orthotic. Data may also facilitate generation of animation that accurately depicts the positions and/or movements of a user's body; the use of augmented and virtual reality for avatar based applications; and presentation of information.

Unique pads, called cuboid lifts, cuboid inserts, or balance-enhancing textured insoles, prevent falls and improve balance by producing site-specific stimulation of different types of cutaneous receptors located along the outer sides of the foot. These cutaneous receptors play a key role in maintaining balance. The outer placement also makes them important in preventing lateral falls, which are far and away the most likely to result in injury. Domes on the upper side of the cuboid inserts increase feedback from the cutaneous receptors as the center of pressure of the person wearing the cuboid inserts moves too far to the outer side of the midfoot. These cuboid inserts are also helpful when managing ankle sprains, as this common injury frequently results in impaired balance.
