An in-line roller skate includes a boot portion and a lower frame portion. The boot portion is fabricated of a first material that is polymeric while the lower frame portion is fabricated of a second material wherein the second material is characterized by a greater degree of stiffness than the first material. The boot and the frame portion are joined by the frame being inserted into a mold designed to form a boot portion such that when the first material is injected into the mold, the first material flows over a portion of the frame and solidifies thereover sufficiently to join the boot and the frame.
