SKATE OR OTHER FOOTWEAR
A skate (e.g., an ice skate) for a skater (e.g., a hockey player). The skate comprises a skate boot for receiving a foot of the skater and a skating device (e.g., a blade and a blade holder) disposed beneath the skate boot to engage a skating surface (e.g., ice). At least part of the skate boot and optionally at least part of one or more other components (e.g., the skating device) may be constructed from one or more materials (e.g., foams) molded by flowing in molding equipment during a molding process (e.g., injection molding or casting). This may allow the skate (or other footwear) to have useful performance characteristics (e.g., reduced weight, proper fit and comfort, etc.) while being more cost-effectively manufactured. Other articles of footwear are also provided.

Footwear component manufacturing methods
Physical foaming a footwear component with a single-phase solution of a polymeric composition and a supercritical fluid is provided. The method include temperature conditioning a mold and then engaging the mold with a robot that conveys the mold to a press. At the press a gas counter pressure is applied to a cavity of the mold before injecting a single-phase solution of a polymeric composition and a supercritical fluid into the cavity of the mold. The process continues with releasing the gas counter pressure from the cavity of the mold and then removing the footwear component from the cavity of the mold. The parameters of the method are configured for the formation of the footwear component in an automated manner.
FOAM ARTICLE WITH ENHANCED PROPERTIES
A foam article, such as a cushioning element for an article of footwear, apparel or sporting equipment is provided that comprises a foam component, such as a midsole, having a number of beneficial physical characteristics. The cushioning element is a low-density foamed component with a surface skin that encases the remaining foam volume. The cushioning element has a number of foam volumes, arranged to achieve a more consistent foam component. Additionally, the cushioning element includes a series of concentric ridges extending radially outwardly from injection gate vestige locations, and a number of striation bands near the perimeter of the cushioning element. The location of the gate vestiges can be beneficially arranged to produce intersecting flow boundaries that are located away from key strain areas of the cushioning element. The cushioning element is more environmentally-friendly, requiring less energy to produce while still providing acceptable energy return and low density.
METHOD FOR PRODUCING MULTI-LAYERED ARTICLES IN AN INJECTION-MOULDING PROCESS
An injection-molding process for injecting a shoe soling including at least two adjacent injection-molding layers onto a shoe upper drawn over a shoe last, uses a mold cavity including a frame, the cavity being covered at the top by the upper also serving as a mold cover, with plastic material being injected into the cavity below the upper. To produce two adjacent injection-molding layers of plastic materials having different properties and reaction times in one operation, i.e. without needing an interim mold opening, before covering the cavity a film is clamped over it by a clamp mounted on the frame. When filling the cavity, the space below the film is first filled with plastic material to produce the first injection-molding layer and then, to produce the adjacent second injection-molding layer, the space above the film is filled with plastic material. Plastic materials are used that inseparably attach to the film.
Method of making an article of footwear with a segmented plate
A method of making an article of footwear is disclosed. The method may generally include placing a first rigid member into a first region of a molding cavity and placing a second rigid member into a second region of the molding cavity. The first rigid member may be spaced from a first cleat and the second rigid member may be spaced from a second cleat. A second material may be injected into the first region and into the second region to form a sole comprising a first plate member and a second plate member.
OVERMOLD DIRECT ATTACH SOLE
Joining a bottom unit, such as an athletic shoe sole, with an upper is achieved with an over molding process. A midsole core may be formed with a direct attach to an underfoot portion of the upper. The forming of the midsole core may be achieved with open cast molding or injection molding, for example. A shell may encapsulate the midsole core and also mechanically engage with the upper to further join the bottom unit with the upper. The shell and the midsole core may be formed from an elastomeric polymer such as polyurethane, thermoplastic polyurethane, ethyl-vinyl acetate, and/or silicone-based materials.
Shoe, sole assembly for a shoe, method for manufacturing a sole assembly, and method for manufacturing a shoe
A shoe according to the invention comprises an upper assembly comprising an upper portion (10) having an outer material (11) for surrounding a foot and a lower portion (20) having at least a breathable layer (21). The shoe also comprises a sole comprising a ventilating container element (113) having a bottom part (103) and a side wall (102) surrounding said bottom part (103) so as to form an inner space of the ventilating container element (113), the ventilating container element being arranged below and attached to the upper assembly, and a filler structure or material (61; 62; 63; 64; 65; 112) allowing for air flow through it placed in the inner space of the ventilating container element (113).
FOOTWEAR HAVING POLYURETHANE BRIDGE LAYER JOINING SOLE AND UPPER AND METHOD OF MANUFACTURING SAME
The present invention is generally related to an article of footwear, in particular, to an improved article of footwear that has a polyurethane bridge layer joining sole and upper, without having to use glue or some other bonding agent and a method of manufacturing such an article of footwear.
Skate or other footwear
A skate (e.g., an ice skate) for a skater (e.g., a hockey player). The skate comprises a skate boot for receiving a foot of the skater and a skating device (e.g., a blade and a blade holder) disposed beneath the skate boot to engage a skating surface (e.g., ice). At least part of the skate boot and optionally at least part of one or more other components (e.g., the skating device) may be constructed from one or more materials (e.g., foams) molded by flowing in molding equipment during a molding process (e.g., injection molding or casting). This may allow the skate (or other footwear) to have useful performance characteristics (e.g., reduced weight, proper fit and comfort, etc.) while being more cost-effectively manufactured.
