Skate with Injected Boot Form

A hockey skate (5) comprises a boot form (10) including a lower portion (12) molded to an upper portion (14), with the lower portion (12) comprising a first plastic material having a first flexural modulus, and the upper portion (14) comprising a second plastic material having a second flexural modulus that is lower than the first flexural modulus; and a skate quarter (22) attached to the upper portion (14) of the boot form (10). The hockey skate (5) 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 (10). 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 (52) of the boot form (10), 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 (54) of the boot form (10). Additional skate components may then be attached to the boot form (10).
