To provide skate shoes having both high rigidity and lightweight property by providing a support body having a hollow sectional internal cavity having a closed profile, and constituting the structure of the skate shoes from a skating traveling means and the support body of the traveling means to be fixed to the shoe of a user.

This structure of skate shoes has a support body 2 of a blade holder for fixing a blade 3 to a shoe, both V-shaped sectional side parts 8a, 8b thereof are converged in the top part for fixing the blade 3, and mounted on a mounting member 7 in both the opposite ends to regulate a hollow sectional closed profile 6. The support body 2 is formed of plastic material by injection molding, and a cavity 5 is formed in the inner part by gas blowing molding technique, so that the inner part forms a substantially tubular strong structure. The blade 3 reduced in height and thickness can be used because of the torsional rigidity produced from the special geometric structure of the hollow section, and the weight of the whole skate shoes can be thus reduced.
