A footbed having at least one of a thickness adjustment panel and a lateral adjustment fin, each configured to be moved between a first configuration and a second configuration, the first and second configurations providing different fits of a shoe into which the footbed is inserted.

A pressure sensing insole according to an embodiment of the present invention includes: a first electrode layer including a first conductive region; a first adhesive layer disposed on the first electrode layer and including an insulating region; an intermediate layer disposed on the first adhesive layer; a second adhesive layer disposed on the intermediate layer and including an insulating region; and a second electrode layer disposed on the second adhesive layer and including a second conductive region.

A shoe has a sensor system operably connected to a communication port. Performance data is collected by the system and can be transferred for further use via the communication port. The shoe may contain an electronic module configured to gather data from the sensors. The module may also transmit the data to an external device for further processing. Users can use the collected data for a variety of different uses or applications.

A pressure-relieving footwear is an apparatus that supports and comforts a user's foot. The apparatus absorbs shock that traverses through the footwear, limiting the impact against the foot of the user. The apparatus includes a footwear, a cushioning layer, a support layer, and a first shock absorbing pad. The footwear protects user's foot and enhances the outfit of the user. The footwear includes an insole, an outsole, and an elongated heel. The outsole includes a forefoot portion and an aft portion. The cushioning layer absorbs the shock and the support layer cradles the foot. The insole is connected across the outsole. The cushioning layer is connected across the insole, opposite to the outsole. The support layer is connected across the cushioning layer, opposite the insole. The elongated heel is connected adjacent to the outsole. The first shock absorbing pad is integrated into the footwear, adjacent to the forefoot portion.

An insole assembly is provided comprising an insole having an upper surface upon which an underside of a foot may contact and be supported. The insole assembly has at least one protrusion which projects away from the upper surface of the insole. At least one of the protrusions is detachably connected to the insole. The protrusions may be interchanged to customize an insole assembly to provide enhanced cutaneous stimulation of targeted regions of a foot.

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.

Shoe insert devices that absorb shock and that redistribute forces within a user's foot and/or knee during use are disclosed. The shoe insert devices comprise a hindfoot insert portion configured to be positioned within a shoe and extend beneath a hindfoot portion of a sole of a foot of the user with a top side of the hindfoot insert portion facing the sole. The hindfoot insert portion is resilient at least in a thickness direction extending between the top and bottom sides thereof. The hindfoot insert portion comprises a fascia projection extending upwardly from the top surface positioned medially between medial and lateral sides of the hindfoot insert portion and being spaced distally from the proximal end, and a lateral projection extending at least one of upwardly from the top surface and downwardly from the bottom surface positioned proximate to the lateral side and distal to the fascia projection.

An orthopedic insole may include at least one strength layer and at least one shock absorbing layer. In one embodiment, the strength layer may be relatively rigid and includes a heel portion and an arch portion, contoured to fit the plantar or bottom surface of the foot to provide arch support. The shock absorbing layer may include a plurality of shock absorbing cells such as recoverable honeycombs or any other negative stiffness structure with the capability to recover. A gait analysis that may include an individual's weight transfer trajectory may have to be conducted to determine the structure of the shock absorbing layer. The orthopedic insole may further include an adjusting layer to supplement the strength layer and the shock absorbing layer to make adjustment to the orthopedic insole if needed.

Improved soles and insoles for shoes, in particular sports shoes, are described. In an aspect, a sole for a shoe, in particular a sports shoe, with at least a first and a second surface region is provided. The first surface region comprises expanded thermoplastic polyurethane (“TPU”). The second surface region is free from expanded TPU.

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.
