This document discloses a process for manufacturing recyclable injection molded microcellular foams for use in, footwear components, seating components, protective gear components, and watersport accessories. The process includes the steps of providing a thermoplastic polymer which comprises at least one monomer derived from depolymerized post-consumer plastic, inserting a fluid into a barrel of a molding apparatus. The fluid is introduced under temperature and pressure conditions to produce a super critical fluid. The process further includes mixing the thermoplastic polymer and super critical fluid so as to create a single phase solution, and injecting the single phase solution into a mold of an injection molding machine under gas counter pressure. The process further includes foaming the single phase solution by controlling the head and temperature conditions within the mold.

An insole having, a base layer, a top layer fixedly secured to the base layer, a middle layer comprised of the base layer and the top layer positioned between the base layer and the top layer, a pressure projection extending upwardly from within the middle layer and extending past an upper surface of the upper layer, the projection including a disc fixedly secured within the middle layer, an annular ring fixedly secured atop the disc, a circular metal insert fixedly secured atop the disc within the annular ring, the circular metal insert having a horseshoe-shaped aperture therein. The insole may also include projections either positioned proximate an inside arch and/or positioned proximate an outside arch. The insole may also comprise a projection positioned proximate to a midfoot region.

A disposable insole pad includes an absorbent layer, a removable skin adhesive, a first release liner, and an anti-slip member. The removable skin adhesive is attached to the top surface of the absorbent layer, and the anti-slip member is attached to the bottom surface of the absorbent layer. The removable skin adhesive is intended to be removably attached to a user's foot, and a first release liner is provided to cover the removable adhesive. The user wears the present invention by removing the first release liner and attaching his foot to the removable skin adhesive, and then, he wears a shoe such that the anti-slip member is to be in contact with a shoe insole.

A footbed for use in footwear is provided. The footbed assembly includes a resilient, flexible material (e.g. EVA or PU foam) that extends the entire length of the footbed. a heel plate made from a material that is more rigid (plastic, carbon fiber) than the resilient foam attaches to the flexible material. The shape of the resilient footbed defines a geometry that provides support and comfort to the user by reducing peak pressures, improving cushioning, and enhancing foot support. The resilient foam and heel plate defines the shape of the midfoot R2 and rearfoot R1 of the footbed while the resilient flexible foam continues forward to define the shape of the forefoot R3 region of the footbed.

A shoe insole includes an insole padding having a bottom surface and a top surface. The insole padding is comprised of vertically oriented non-woven fibers. The non-woven fibers that comprise the insole padding are generally vertically oriented relative to the bottom surface and the top surface of the insole padding.
