A shoe construction having an outsole wherein the exterior face includes a forefoot section, a midfoot section, and a heel foot section, the forefoot and midfoot sections including a stair step pattern, the heel foot section including a plurality of projections, the interior face of the outsole including a forefoot cavity having a plurality of wavy rib members and a hind foot cavity having a plurality of straight rib members, a dual density midsole having a first density in the forefoot area and a second density in the hind foot area, and an insole receivable within the midsole and having a top face which includes a scored geometric pattern forming a plurality of non-linear grooves and projections some of which spiral outwardly from around the arch area and some of which extend into the forefoot and hind foot areas, and a pair of cushioning members receivable respectively within the forefoot and hind foot cavities of the outsole.

A three-layered shoe construction including an outsole having a shoulder portion and a plurality of two different types of grooves, one set of grooves being wave-like channels and one set of grooves being substantially straight, the grooves creating flow channels to guide liquid off the outer surface of the outsole and providing additional flexibility; a dual density midsole having an angled portion and a first density in the forefoot area and a second density in the hind foot area, the second density being greater than the first density, the angled portion of the midsole mating with the shoulder portion of the outsole; and an insole having a plurality of apertures that cover the top face. The specific construction associated with the outsole, midsole and insole enhance traction, flexibility, cushioning, comfort, breathability and water displacement.

An orthotic support structure or shell may be used with footwear intrinsically or as a removable and transferable device. The footwear may be a sandal assembly including a sole, a strap and an orthotic shell. The strap is attached to the sole and configured to secure the sole against the foot. The orthotic shell is positioned within the sole and formed from a semi-rigid material. The orthotic shell includes a heel portion configured to support a heel region of the foot, and a midfoot portion connected to the heel portion and configured to support an arch region of the foot, the midfoot portion comprising an arched shank having a curved convex shape. The arched shank is configured to deflect under a downward force applied thereon which reactively rotates the heel portion toward the heel region of the foot.

A removable insole for insertion into footwear, comprises a forefoot portion integral to the insole and extending at least to a metatarsal of a foot and including a resilient layer, the resilient layer including at least two non-contiguous resilient layer sections (including a big toe section). The at least two non-contiguous resilient sections include at least four resilient layer subsections in some embodiments, a continuous rear portion that includes a medial longitudinal arch support portion, a heel surrounding portion and a lateral longitudinal arch support portion; and a heel portion. In some embodiments, the forefoot is customizable by having different levels of hardness for the subsections and big toe section. The insole is therefore tailored a particular sport. The medial longitudinal arch support portion includes a detachable cushion configured to adjust a height of the medial longitudinal arch and to support the foot during pronation of the foot.

A method of forming a castless orthotic for a patient's foot in need thereof. The method comprises preparing an orthotic template for the foot wherein the template extends between a heel end and a toe end. In preparing the template the steps of attaching a three-quarter length or full length upper thermoplastic material to a or three-quarter length lower thermoplastic material, or providing a thermoplastic material having a variable thickness such that said thickness decreases from said heel end to said toe end is provided. Then attaching an outer lower layer to the lower thermoplastic material and attaching an outer upper layer to the upper thermoplastic material, or attaching an outer layer to each face of the variable thickness thermoplastic material and heating the prepared orthotic template for a predetermined period of time at a predetermined temperature to soften the orthotic template. A wrap is then placed on top of the foot foam and the foot of the patient is placed on top of the wrap and foot foam. The patient's foot is lifted and the heated orthotic template is placed on top of the wrap and then placing the patient's foot on top of the heated orthotic template. The wrap is placed about the longitudinal axis of the foot to retain the heated orthotic template intermediate the sole of the foot and the foot foam whereby the sides of the orthotic template are particularly supported by the wrap. The method further includes ensuring the foot is positioned over a cuboid support and a medial longitudinal arch support wherein the cuboid support is disposed on the outside of the bottom of the foot and the cuboid support is moved to push the foot upwardly until a resistance is felt, and where the foot is also positioned over the medial longitudinal arch support which is then pushed and pulled upwardly until the foot is moved into a neutral position or if it is unable to be translated or rotated due to until it reaches its end range of motion. At this time, the heel of the patient's foot is lifted to place their weight substantially on the front of their foot and a coolant is applied to at least the heel end of the orthotic template.

A footwear stability and comfort system (footwear system) comprises an insole having an anatomic footbed, and footwear incorporating the insole. The disclosed footwear system is designed to provide a cradle around the bottom and sides of the foot for support during flexion while walking, and for proper placement of the foot within the shoe.

A plurality of orthotic systems are provided. One bi-layer system is constructed from a single sheet of fabric that is molded into two layers. One tri-layer system includes a base layer; a mid-layer, and an upper layer. The upper layer is joined to the mid-layer and the mid-layer is joined to the base layer. The coupling of the base layer, the mid-layer and the upper layer create a rear spring section, a mid-spring section and a front spring section in which the upper layer is suspended over the mid-layer and the heel portion is suspended on the proximal heel end of the base layer.

The Sprain Arrestor is an orthotic wedge made of cut and shaped industry standard multidurometer tri-laminate material which by its size and shape and placement inside the shoe offers an inexpensive alternative to bulky bracing and or elastic minimally supportive bandages and wrappings which can restrict circulation. Its use is totally dependent upon the need of the user.

Embodiments provide an insole sandal and a shoe without a tongue. The insole sandal has a first surface configured to interface with a foot of a wearer; and a second surface configured to interface with a ground surface, and a bottom of an interior of a shoe. The insole sandal further has a strap configured to hold the insole to the foot of the wearer when the insole sandal is worn as a sandal. The first surface and the second surface are on opposite sides of one another. The insole sandal is configured to fit within the interior of the shoe. The shoe is configured to receive the insole sandal in its interior. The bottom of the insole sandal and an inner sole of the shoe may have complementary protrusions and depressions.

An orthopedic shoe appliance includes a pad for providing support for midfoot arches, the second metatarsal, and the third metatarsal of a foot, wherein the pad does not provide substantial support under a heel of the foot or under the first metatarsal, the fourth metatarsal, and the fifth metatarsal. A method for manufacturing an orthopedic appliance includes obtaining a pad; and shaping the pad to provide support for midfoot arches, the second metatarsal, and the third metatarsal of a foot, but not provide substantial support under a heel of the foot or under the first metatarsal, the fourth metatarsal, and the fifth metatarsal.
