A method for manufacturing a pad with dynamic massage bubbles includes: preparing an upper-half foam substrate and a lower-half foam substrate; and bonding the upper-half foam substrate and the lower-half foam substrate together by means of hot press so that air bubbles are formed therebetween. Particularly, then form-setting bake is performed under a progressively decreased baking temperature, so that as the pad is cooled gradually, the air bubbles are well shaped. The method provides improved dimensional control of air bubbles, thereby significantly enhancing manufacturing precision and yield.

Articles of footwear may be placed in the steaming system to help customize the articles of apparel for a user's fit and comfort. The steaming system can be configured to be portable and carried by a person.

A method for manufacturing a recycled carbon fiber underlay, which mixes recycled carbon fiber material with nylon or composite plastic and forms an elastic recycled carbon fiber injection particle material, and under an injection process condition, the recycled carbon fiber injection particle material is injected and molded into a recycled carbon fiber underlay. The recycled carbon fiber arch insole comprises a recycled carbon fiber underlay manufactured by the aforementioned manufacturing method, together with the data of podiatric medical big numeric database of human factors engineering for the innovative design of mechanical insole products and the application development of recycled materials to encourage recycling to reduce carbon emissions, while improving the function, durability, and comfort of insole inserts.

The present invention is to provide a thin foam skin having cushioning effect and the excellent grip performance without slip so as to substitute the fabric adhered to the top part of a footwear insole, and realize a footwear insole and a manufacturing method thereof, wherein the foam skin for substituting a fabric is preferably made using polyurethane resin so as to prevent the slip phenomenon when adhering the foam skin to the top part of an insole and smoothly absorb sweat by using the hydrophilic property, thereby maintaining pleasant wearing feeling all the time even during long time exercise.

Disclosed are a shoe insole and its manufacturing method. The method includes the steps of crushing a rubber foam material into irregular primary crushed particles, covering a mixed elastomeric material onto a surface of the primary crushed particle uniformly, using a pressurizing, heating and curing method to form a primary modified foam material, crushing the primary modified foam material again to form irregular secondary crushed particles, covering the secondary crushed particles uniformly mixed with the elastomeric material onto a surface of the secondary crushed particle, and using the pressurizing, heating and curing method to form a secondary modified foam material similarly. The shoe sole made of the secondary modified foam material has good breathability, elasticity, comfortability and compressive strength.

Disclosed herein are improved cross-linked resilin compositions and methods of making these improved compositions. These include new methods of cross-linking resilin compositions, use of polar nonaqueous solvents for adjusting material properties of cross-linked resilin solid compositions, and resilin foam compositions and methods of making the same.

In one aspect, the occupied volume ratio of the cushioning portion is larger in a medial forefoot area than a lateral forefoot area, is larger in a medial midfoot area than a lateral midfoot area, is larger in a medial rearfoot area than a lateral rearfoot area, is smaller in the medial forefoot area than the medial midfoot area, is smaller in the lateral forefoot area than the lateral midfoot area, is equal in the medial midfoot area and the medial rearfoot area or is smaller in the medial midfoot area than the medial rearfoot area.

A mold includes a seat, a plurality of guiding tracks, a plurality of positioning grooves, a plurality of telescopic rods, a plurality of elastic members, at least one sliding device and an insole material. The guiding tracks are disposed on the seat. The positioning grooves are disposed on the seat and are corresponding to the guiding tracks, respectively. The telescopic rods include a plurality of abutting portions, respectively. The elastic members are disposed in the seat for applying a plurality of restoring forces to the telescopic rods, respectively. The sliding member is movable along the track to press the abutting portions, and the abutting portions are connected tightly to each other so as to position the telescopic rods. The insole material is disposed below the telescopic rods for molding an insole.

An injection molding method is provided. A molding device is provided, and the molding device includes a first mold, a second mold over the first mold, and a middle mold between the first mold and the second mold. A first component is disposed on the second mold. The middle mold is engaged with the first mold and the second mold to form a mold cavity after the first component is disposed on the second mold. A polymeric material is injected into the mold cavity to surround the first component. An article formed by the polymeric material and the first component is obtained.

An article includes a foamed member including a polymeric material, and a core embedded in the foamed member, the core includes a first surface, a second surface and a sidewall, the foamed member covers at least a portion of the first surface, and covers the entire sidewall and the entire second surface. A method of manufacturing an article includes providing a molding device including a first mold and a second mold, the first mold includes a supporting member protruded from an inner wall. The method further includes disposing a core on the supporting member; disposing the second mold over the first mold to form a mold cavity, the core is disposed within the mold cavity; injecting a first material into the mold cavity; and foaming the first material to form a first foamed member, wherein at least a portion of the first foamed member is in contact with the core.
