Abstract: A boot form for a hockey skate is made of multiple plastic materials having different hardness properties, or different flexural moduli, and is formed via an injection-molding process or another similar process. One or more of the plastic materials may be reinforced with fibers of glass, carbon, aramid, or another stiffening material to strengthen one or more regions of the boot form. For example, pellets of a first plastic material having a flexural modulus of approximately 190 MPa (e.g., a polyamide elastomer block amide) may be injected into a mold to form a softer upper region of the boot form. And pellets of a second plastic having a flexural modulus of approximately 20,000 MPa (e.g., a Nylon 12 with long glass fibers) may be injected into the mold to form a stiffer lower region of the boot form. Additional skate components may then be attached to the boot form.

Varying the stiffness of the lower portion of the boot form in this manner allows the flexibility of different sized boots to be substantially equalized. A skate quarter and other skate-boot features may readily be attached to the upper portion of the boot form via stitching, rivets, or other connectors. The boot form also may include an integral toe cap having a flange or other element to which the skate tongue and other elements may be connected.

Abstract: A protective cover fits over the top of a hockey skate boot. The cover has a vertically-split heel that is contiguous with an open bottom, and includes enough flexibility and tension that the cover can be flexed open diagonally from the split heel to fit over the top of the hockey skate boot, and then released to substantially conform to the instep, sides, ankles, and a portion of the heel in a tensioned fit. The preferred material for the cover is a high grade polycarbonate. The high grade polycarbonate is advantageous over other materials known in the art of covers based on the specific strength, impact resistance and elongation characteristics of high grade polycarbonates. The temperature ranges that the cover may be used in vary significantly and the high grade polycarbonate provides for optimal protection and performance in the wide temperature ranges.
