Abstract
A unitary, homogeneously molded boot and support for a roller or ice skate is provided as a one piece unit having no juncture between the boot and the support. The boot may be molded with either a roller skate or an ice skate chassis by forming the chassis of a first plastic having a high stiffness characteristic when cooled. The chassis is then placed in a boot injection mold and a second heated plastic is injected into contact with the chassis. The second plastic is more flexible when cooled than the first plastic, but is compatible therewith so that the two flow together and form an integral, unitary structure. The unitary boot is formed with a pivotal upper due to three slits in the boot which cooperate to provide opposite fulcrum sections about which the upper pivots.
