An insole comprising a shell component and a chassis component. The shell component comprises support bars that define framing apertures and the chassis component comprises undercut channels that define raised pod sections.

The invention relates to a device comprising: a first layer (11) of a thermoformable material that is inelastically deformable in a thermoforming temperature range, a second layer (1) of a viscoelastic material that is elastically deformable in a temperature range including a use temperature range of the device and the thermoforming temperature range, and wherein: the use temperature range is lower than the thermoforming temperature range, the first layer is bonded to the second layer, the thermoformable material is elastically deformable and more rigid than the viscoelastic material in the use temperature range, the thermoformable material is less rigid than the viscoelastic material in the thermoforming temperature range.

An insole having a magnetic propulsion insert, provided with magnets or magnetic charges inside thereof, which provides a magnetic distracting effect in the midfoot and the hindfoot of a user. The insole formed by two sheets is merged in the fore third, known as the forefoot zone leaving the sheets in the midfoot zone and the hindfoot zone separated. The magnetic propulsion insert is a structure formed by a sheet which bends in its midpoint to create two separate surface and with identical magnetic charges. These generate a propulsion effect by the force or impulse produced by the magnetic charges. In the rear thirds of the insole, the top sheet has charges in its bottom surface, and in these two thirds the bottom sheet has the same charges as the top surface. This is to generate the propelling effect in the foot heel of a user.

A footwear insert assembly including a pair of integrally formed full length footbeds adapted for insertion within an item of footwear and a heel insert adapted for insertion in the item of footwear beneath one of the full length footbeds of the pair of integrally formed full length footbeds such that the full length footbed and the heel insert cooperate with the footwear to raise a heel portion of the full length footbed. The pair of full length footbeds include a first contoured footbed having a contoured arch portion, the contoured arch portion of the first contoured footbed having a thickness providing a first degree of arch support, and a second contoured footbed comprising a second contoured footbed having a contoured arch portion, the contoured arch portion of the second contoured footbed having a thickness that is less than the thickness of the contoured arch portion of the first contoured footbed, the contoured arch portion of the second contoured footbed providing a second degree of arch support, wherein each of the first contoured footbed and the second contoured footbed is adapted for interchangeable insertion within an item of footwear to thereby produce a supportive feel when worn.

The present invention relates to methods and systems for predicting biomechanical response to wedged insoles. In accordance with one aspect, a method for predicting a biomechanical response to a wedged insole is provided. In a further aspect, a system for predicting a biomechanical response to wedged insole is provided.

Methods of using a foot device are disclosed herein. The foot device includes a generally U-shaped portion having an arcuate portion and first and second legs extending from the arcuate portion. Each leg has an end and a relief area disposed adjacent the respective end. A method of using the foot device comprises engaging the arcuate portion with a heel of a foot to form a first point of contact; positioning the relief area of the first leg proximate a fifth metatarsal head of the foot such that the fifth metatarsal head drops to form a second point of contact; and positioning the relief area of the second leg proximate a first metatarsal head of the foot such that the first metatarsal head drops to form a third point of contact, wherein the first, second, and third points of contact form a triangle-shaped contact surface.

An orthotic for a foot having a top side and a bottom side, the bottom side having flexion zone located between the medial and the lateral side of the orthotic at a position corresponding to the posterior metatarsal phalangeal joint of the foot and 25 mm behind; and/or the heel section of the bottom side of the orthotic pitched so that the height of the rear of the orthotic is greater than the innermost section of the heel; and/or the top side having a raised section located at a position corresponding to the medial side of the calcaneus of a foot.

In embodiments, an adjustable orthotic foot device may include a shell layer including an upper surface and a contoured lower surface, and a soft insole layer coupled to the upper surface of the shell layer, the soft insole layer defining an arch support structure on an upper surface of the soft insole layer along a medial edge of the soft insole layer. The adjustable orthotic foot device may further include one or more structural support inserts configured to be removably inserted within a pocket formed between the shell layer and the soft insole layer in order to adjust an arch height of the arch support structure. In embodiments, the one or more structural support inserts may be defined by a curved lateral edge and a convex curved medial edge.

A foot engagement device includes a generally U-shaped portion having an inner edge, an outer wall, and a tapered upper surface extending from the inner edge to the outer wall. The upper surface tapers between 1 degree and 45 degrees from the inner edge to the outer wall.

Apparatus and associated methods relate to a footwear liner system including a liner portion to be worn on a foot and a releasably attachable external insole, releasably attachable to an underside of the liner. In an illustrative example, the external insole may be configured to provide arch support for the insole independent of the liner's conformability to the foot. In an illustrative example, the liner is pliable and moldable. In an illustrative example, the external insole includes a stiff arch support that is independently and releasably attachable to the liner. Various embodiments may advantageously provide an economical sports boot liner assembly with user-integratable custom insole.
