Presented are footwear sole structures with foot-cushioning insoles movably mounted onto impact-attenuating midsoles, methods for making/using such sole structures, and footwear fabricated with such sole structures. A multilayered sole structure assembly includes an insole movably mounted on a midsole. The midsole is formed with a first compressible material and includes opposing upper and lower midsole surfaces, multiple protrusions projecting from the upper midsole surface, and multiple pockets recessed into the upper midsole surface and interleaved with the midsole protrusions. The insole, which is formed with a second compressible material distinct from the first compressible material, includes opposing upper and lower insole surfaces, multiple protrusions projecting from the lower insole surface and interleaved with the midsole protrusions, and multiple pockets recessed into the lower insole surface and interleaved with the insole protrusions. Each midsole protrusion nests within a respective insole pocket, while each insole protrusion nests within a respective midsole pocket.

Disclosed herein are insoles useful for treating skin injuries on a foot, for instance ulcers. The insoles are customizable for each patient's foot and can include various portions of differing softness, depending on the needs of the patient. For instance, it can be beneficial for certain sections of the foot to contact a firmer material, whereas other sections contact a softer material. Some, or all, of the materials can include one or more biofidelic skin simulant materials. Thus, various implementations include one or more regions that can include the same or different materials. For example, a custom insole can include a heel support region, a midfoot support region, and a forefoot support region, and the support regions can be subdivided into medial and lateral support regions or toe regions. One or more regions may have a custom isolation segment to prevent the progression of ulcers and/or expedite wound healing.

An article of footwear includes an upper having a fastening mechanism, a sole, and a frame having an exterior surface and an interior surface. The sole includes a midsole structure and an outsole structure. The interior surface of the frame is adjacent portions of the midsole structure, the outsole structure, and the upper. The frame further has a lattice-work structure formed by a plurality of apertures extending through the interior and exterior surfaces of the frame such that at least some of the portions of the midsole structure, the outsole structure, and the upper adjacent the interior surface of the frame are exposed through the plurality of apertures. The fastening mechanism includes a fastening member extending through at least one aperture of the plurality of apertures of the frame.

This document discloses algae-derived flexible foams, whether open-cell or closed-cell, with inherent antimicrobial and flame resistant properties, wherein a process of manufacturing includes the steps of: harvesting algae-biomass; sufficiently drying the algae biomass; blending the dried algae biomass with a carrier resin and various foaming ingredients; adding an algal-derived antimicrobial compound selected from various natural sulfated polysaccharides present in brown algae, red algae, and/or certain seaweeds (marine microalgae); and adding a sufficient quantity of dried algae biomass to the formulation to adequately create a fire resistant flexible foam material.

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.

A shoe extension for gait modification includes a vamp section, a base section, an attachment strap, and a restraining mechanism. The vamp section is connected to a top surface of the base section forming a receiving slot. A toe box of a shoe worn on a healthy limb is slidably positioned into the receiving slot such that the base section is positioned along an outsole of the shoe. The attachment strap is utilized to establish a connection with the shoe. By increasing an overall length of the footwear worn on the healthy limb, a speed of motion of the healthy limb may be reduced in order to increase weight bearing on the unhealthy limb. The restraining mechanism, which is preferably integrated into a bottom surface of the base section, may also be used to reduce the speed of motion of the healthy limb.
