An orthopedic walking boot promotes rapid healing of diabetic foot ulcerations by lowering the maximum peak pressure imposed upon the foot. The walker has a hard unyielding shell which is designed for walking. The shell closely and rigidly supports a mid-sole in a foot-shaped bed. The mid-sole has a foot-shaped cavity with rounded sides adapted to form resilient support for the heel, arch and sides of a foot in addition to the bottom of a foot. A conformable inner-sole is adapted to fit over the foot-shaped cavity in the mid-sole and be compressed in response to foot pressure between the sides and bottom of the foot and the sides and bottom of the foot-shaped cavity in the mid-sole thereby compensating for small differences between the shape of the foot and the shape of the cavity. Weight applied to the foot is transferred to the walking shell by contact between the sides of the foot, arch, and heel and the arch, heel and sides of the foot-shaped cavity as well as the bottom of the cavity thereby decreasing the peak or maximum unit pressure on the plantar surface of the foot. A breathable bootie which wraps the foot and lower leg in a protective “cocoon” is preferably secured to the upper surface of the insole thereby preventing foreign materials from entering the foot cavity.

An stretch resistant plantar fascia support system is provided. The stretch resistant plantar fascia support system is adhesively applied to the foot of a patient for providing relief from plantar fasciitis.

An article of footwear and insert for an article of footwear are provided with means for stimulating cutaneous pressure sensation from the perimeter of the plantar surface (sole) of the foot. Increasing cutaneous sensation from the perimeter of the plantar foot surface provides the central nervous system of the wearer of the footwear with an increased ability to detect and react to shifts of the body's center of gravity toward the edges of the feet which, if left uncorrected, could result in a loss of balance or a fall. An insole is disclosed which is provided with an elongate member or a series of protrusions which form a narrow ridge in close proximity to the perimeter of the insole, the ridge being adapted to protrude upwardly against the plantar foot surface along at least a portion of the perimeter thereof.

A device for treatment of plantar fasciitis and/or Achilles tendonitis that comprises:

• (a) a calf strap removably engagable to the calf of a leg;
• (b) a foot assembly removably engagable to the foot of the leg such that when the device is worn the assembly can be positioned proximate to the ball of the foot intermediate to the midfoot and forefoot areas of the foot to secure it to the foot; and
• (c) a substantially inelastic tension member connectable between the calf strap and the foot assembly in a tensioned manner

such that when the device is worn the plantarflexion of the ankle is limited such that the plantar surface of the foot is held in a neutral to slight dorsiflection.

Also, a method of treating plantar fasciitis and/or Achilles tendonitis that comprises applying a such a device so as to maintain the plantar fascia and other structures on the plantar surface of the foot in a neutral to slight dorsiflection.

An apparatus and method for determining contours of a patient's foot. The apparatus includes an alignment section that orientates the foot relative to an optical imaging section. The alignment section includes at least one support member located proximate a focal length of the imaging section, that engages the plantar surface substantially only in the immediate area of the fifth metatarsal head of the foot. The support generates a dorsally-directed load that locks the midtarsal joint. The alignment section further includes a heel stirrup and a laser beam or other reference line for aligning the second metatarsal head with the distal one-third of the lower leg, to place the subtalar joint in a neutral condition. The foot is thus suspended in space such that the imaging section is able to obtain an accurate measurement of the plantar surface without distortion of the soft tissues or bone structure of the foot.

Footbeds (e.g., in footwear, socks, etc.) for engaging a plantar surface of a wearer's foot include one of the lateral or medial sides having a smooth or substantially smooth feel or surface while the opposite side has a textured feel or surface, e.g., by providing plural raised areas that define the textured feel or surface. Depending on the location of the texturing (lateral side or medial side) and/or the type of ambulatory activity (e.g., running or walking), lower extremity movement during the activity may be affected, e.g., to reduce pronation, reduce maximum eversion, reduce rearfoot range of motion, reduce eversion velocity, reduce plantarflexion when pushing off during a step, reduce inversion at heel strike, reduce eversion range of motion, reduce maximum internal tibial rotation, to increase stability during cutting motions, etc.
