A light-cured anti-slip structure includes an anti-slip layer fixed onto a substrate surface. The anti-slip layer is composed of the light-curing composite, wherein the light-curing composite includes 50 wt % to 100 wt % of photopolymer, 0.5 wt % to 20 wt % of photoinitiator, 5 wt % to 50 wt % of thermosetting polymer, less than or equal to 5 wt % of thermal curing initiator, which are mixed. The photoinitiator receives light energy to trigger a light-curing reaction of the photopolymer. Simultaneously the photoinitiator releases heat to activate the thermal curing initiator, the thermal curing initiator induces a curing reaction of the thermosetting polymer to form the anti-slip layer. The light-cured anti-slip structure provided by the present invention could be quickly cured on the substrate surface, and the manufacturing time and the cost of material could be significantly reduced. A manufacturing method of a light-cured anti-slip structure is provided as well.

Provided is a shoe sole member formed by at least two types of polymer compositions, a first composition and a second polymer composition, including: a first part formed by the first polymer composition; a second part formed by the second polymer composition; and a third part formed by a mixture of the first polymer composition and the second polymer composition between the first part and the second part.

A method of manufacturing a fluid-filled chamber with a tensile element includes manufacturing a tensile element and incorporating the tensile element into a chamber. A first material layer, a second material layer, and a spacing structure having a plurality of support portions and a plurality of gaps may be stacked. The material layers may be located on either side of the spacing structure or on one side of the spacing structure. A strand may be stitched through the gaps to join the material layers and to form the tensile element. The spacing structure may be removed, and the first material layer may be spaced from the second material layer such that segments of the strand extend between the material layers. The tensile element may then be secured to opposite interior surfaces of an outer barrier, and the outer barrier may be pressurized to place the strand in tension.

A midsole molding apparatus which enables production of a high-quality midsole is provided. The apparatus includes a through hole, which passes laterally through a midsole used for a shoe, to be integrally formed, preventing traces of forming the through hole from being left in the through hole and on the periphery of the through hole and a shaft mold crossing the inner space of upper and lower molds, forming extending portions such that the ends of the shaft mold extend beyond the boundary of the inner space, and seating the extending portions in press recesses of the upper and lower molds to seal the insides of the molds so as to prevent raw material from leaking from inside the molds when foaming and forming a midsole, to prevent parting lines and burrs from forming on the inner surface of the through hole passing laterally through the midsole.

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.

A chamber may include a first barrier portion, a second barrier portion, a peripheral bond, an interior bond, and a fold. The first barrier portion defines a first surface of the chamber. The second barrier portion defines a second surface of the chamber, the first surface being opposite the second surface. The peripheral bond joins the first barrier portion and the second barrier portion to form an interior void within the chamber and seal a fluid within the interior void. The interior bond is spaced inward from the peripheral bond and joins the first barrier portion and the second barrier portion. Additionally, the fold is in the second barrier portion and extends away from the interior bond and through a majority of a thickness of the chamber.

Described are methods for manufacturing a plastic component, in particular a cushioning element for sports apparel, a plastic component manufactured with such methods, for example a sole or a part of a sole for a shoe, and a shoe with such a sole. The method for the manufacture of a plastic component includes loading a mold with a first material includes particles of an expanded material and fusing the surfaces of the particles by supplying energy. The energy is supplied in the form of at least one electromagnetic field.

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.

A sole structure for an article of footwear includes a unitary cushioning component comprising a plurality of scrap foam pieces configured as a plurality of different polyhedron shapes and a resin binder securing the scrap foam pieces to one another. The sole structure may comprise a midsole including an outer shell defining a central cavity. The cushioning component may be disposed in the central cavity as a core of the midsole. A method of manufacturing an article of footwear cutting the scrap foam body into pieces, mixing the pieces with a resin binder, and compression molding the mixed pieces and resin binder in a mold to form a cushioning component of a sole structure of the article of footwear.
