Claim:
1. A method of manufacturing a skate boot shell, the method comprising: shaping a tridimensional outer sub-shell to define a first heel portion, a first ankle portion connected to the first heel portion, and two opposed first side portions extending from the first heel and ankle portions, the outer sub-shell having an inner surface; shaping a tridimensional inner sub-shell separately from the outer sub-shell, the inner sub-shell being shaped to define a second heel portion, a second ankle portion connected to the second heel portion, and two opposed second side portions extending from the second heel and ankle portions, the inner sub-shell having an inner surface and an outer surface complementary to the inner surface of the outer sub-shell; shaping a tridimensional reinforcement sub-shell separately from the inner sub-shell and from a material different from that of the inner and outer sub-shells, the reinforcement sub-shell being shaped to have a third heel portion, a third ankle portion connected to the third heel portion, and two opposed third side portions extending from the third heel and ankle portions, the reinforcement sub-shell having an outer surface complementary to the inner surface of the inner sub-shell; inserting the shaped inner sub-shell within the shaped outer sub-shell and the shaped reinforcement sub-shell within the inner sub-shell; and bonding the shaped sub-shells together through lamination, the lamination being performed after the sub-shells are shaped, the lamination being performed with the inner surface of the inner sub-shell in alignment with the outer surface of the reinforcement sub-shell and with the outer surface of the inner sub-shell in alignment with the inner surface of the outer sub-shell, the lamination including applying heat on the sub-shells and pressure on one of the reinforcement and outer sub-shells toward the other of the reinforcement and outer sub-shells, the other of the reinforcement and outer sub-shells resting against a mold surface.
