Disclosed herein is a new roller skate construction in which an improved rigid sandal sole is uniquely combined with a sandal vamp and a pair of skate wheel trucks. The sole is formed in one piece and is provided with integrally molded-in truck support posts and a brake post, all of which project downwardly from the underside of the sole. An ''''orthopedic'''' sole surface, i.e., one in which the foot-engaging contours of the sole are specially contoured to conform closely to and to support completely and comfortably the contours of a human foot, is integrally formed on the upper surfaces of the new sandal skate sole. The vamp is affixed to medial portions of the lateral edges of the one-piece sole and secures the foot of a user directly to the orthopedic surfaces. A sling-back type of buckled foot strap extends across the vamp to secure the heel of the user within and upon the sandal structure formed by the cooperation of the new sole and vamp. A pair of skate trucks, each supporting a pair of roller bearing mounted wheels, are affixed in tandem to the integral truck support posts by a longitudinally extending bolt. Appropriate shock absorber pads of resilient synthetic or rubber material are interposed and compressed between the truck bodies and the bottom surfaces of the posts to enhance a wearer''s comfort when using the new roller skates.
