Skate with injected boot form
First Claim
1. A hockey skate, comprising:
- a boot form including a lower portion and an upper portion molded to the lower portion, a flexibility of material of the upper portion being greater than a flexibility of material of the lower portion such that the upper portion is less rigid than the lower portion, the material of the lower portion being a composite and the material of the upper portion being a composite; and
a skate quarter attached to the upper portion of the boot form.

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.
