A composite material is used for the sole of the boot of an ice skate, in-line skate, or roller skate. The material is a thin layer of resin and reinforcing fibers. Thermoset resins such as polyester resin or epoxy resin, or thermoplastic resins such as polyamides (e.g. Nylon 6, Nylon 6-6, Nylon 12, Nylon 11), acrylics, ABS, polypropylene, polyethylene, etc., may be used. The fibers, such as glass, Kevlar TM or carbon fibers, are encapsulated in the resin in order to increase the flex modulus or stiffness of the sole. The orientation of the fibers and the percentage of fiber content versus resin content will dictate the final rigidity. The fibers can be in short lengths oriented randomly in the resin, or there can be longer strands, either unidirectionally oriented in the resin, or layered or woven to create a bidirectional structure. A preferred material is BioMechanical Composites' Novotek HW-5050 TM material.
