Abstract
Skate comprises a shoe portion (1) a ground touching device (11) and a transition portion (3) which connects the ground touching device (11) to the shoe portion (1). The shoe portion (1) and the transition portion (3) are made in one piece and form a shell of a sandwich construction with a core (5) made of foam plastic and outer layers (6,7) made of plastic reinforced with glass or carbon fibers. The ground touching device (11) may be a metal section fastened by glue in a downwards opening groove (1) formed in the transition portion (3) and adapted to glide on ice or rollers arranged in the groove and adapted to rotate about respective shafts fastened to the transition portion. There is thus provided a very light skate which renders good support to the foot and has little air resistance.
