An insole having a top sheet, a base layer, a forefoot pad, a heel cushion, and stability cradle. The forefoot pad can be made a blown EVA or other material, and the heel cushion can be made of a clear TPR, soft polyurethane or blown EVA. A heel cup surrounds the exterior back by a heel cup, and a heel pod opening and midfoot pod opening is located in the stability cradle for allowing placement of heel pads and midfoot pads in a replacement manner. There is also a soft metatarsal raised dome on the top (foot contact) surface of the insole which would be directly above the metatarsal midfoot area.

The soft boot and liner include a moisture transfer system that includes an inner fabric layer carefully selected from technically advanced fabrics. A series of layers are provided outside the inner liner including foam material layers, spacer fabrics and breathable membranes, in various orders. Encapsulation technology and waterproofing are used as well. The outer fabric layer is also capable of working with the other layers to promote the transfer of moisture. Frothed foams and flocking with fibers are further characteristics of the present invention. The moisture transfer system is incorporated into a soft boot or skate or as a removable liner for a shell boot. Numerous other modifications and applications are disclosed.

The present invention is directed to an adjustable footwear system to provide varying degrees of tightness in different areas of the footwear before and after the footwear is received on the foot. An extensor system is activated to open or close a cavity of the footwear between the upper and an insole. The extensor system can provide loosen the footwear to the foot.

Sole for footwear that includes configurations that improve the cushioning in a user's tread with respect to known soles, comprising a lower layer and a side wall, the lower layer comprising a front part, a middle part and a rear part; in at least one portion of the front or rear part of the lower layer there are at least two protrusions, each arranged and extended transversely to the longitudinal axis of the sole and each of them comprising a first segment in contact with the lower tread and a second segment; between the side ends of each protrusion and the side wall there is a first separation that allows the full bending of each protrusion, the second segment being inclined with respect to the first segment; between two adjacent protrusions there is a second separation so that the second segment rests at least partly on the adjacent protrusion.

A midsole of footwear with an incorporated orthotic support. The midsole includes a soft and flexible member and a more rigid orthotic support. The orthotic support includes a heel cup and an arch support portion that extends forwardly from the heel cup. Embodiments produce the midsole by positioning the orthotic insert between an upper portion of the footwear and an outsole. Then, soft and flexible material is injected into the space surrounding the orthotic. The soft and flexible material subsequently cures forming the multi-part unitary midsole.

A plantar shaped shoe sole constituted by layers includes a mid-sole constituted by a body and elastically compressible protrusions protruding downward from a body lower surface, each having an axial cavity and first holes. An upper surface of the body has holes associated with first holes of each protrusion. First protrusions are arranged at a central area of the heel and forefoot of the body and have a greater protruding height than second protrusions. First and second protrusions have first and second apices, respectively, forming anatomically-contoured curved surfaces, formed at protrusion free ends, opposite the body lower surface. Each axial cavity extends from the upper surface to their respective apex. There are more forefoot region first holes of first protrusions than second protrusions. The sole includes a tread and an elastic plantar supporting structure, at least one seat on the upper surface wherein the apices are positioned on the seat.

This disclosure includes dual-layer insole apparatuses for diabetic foot lesion prevention and related methods. Some insole apparatuses have a body defining a plurality of cavities configured to be coupled to a fluid source such that the fluid source can deliver fluid to vary internal pressures of the cavities, and where the body defines an insole-shaped structure.

An articulated orthotic insert including a first curved member with a tapered edge configured to fit the heel of a foot. An elongated flexible rod is attached to the first curved member at a first end of the elongated flexible rod. A second member is attached to a second end of the elongated flexible rod. The second member has an indented section that accepts the ball of a foot. There are numerous support members attached to the elongated flexible rod in a perpendicular manner. The support members are curved upwards as to support the arch of a foot. The support members are in various lengths and heights to better conform to a foot. The support members are made from a rigid material such that they support the arch of a foot when a foot is placed on the support members.
