Several embodiments of open and closed loop frames substantially elliptical in shape are disclosed for in-line skates. Some embodiments include independent suspension for each wheel. The frame is flexible to provide shock absorption and rebound. The frame stiffness increases with the applied load. The frame stiffness and flexibility may be adjustable. The rocker of the skate is made to vary with the applied load so that the skate has high maneuverability yet is very stable when gliding. The frame includes a boot mounting system which adds no stress concentrations, thus assuring even flex properties over the entire frame, and high durability. Overload protection is included to further enhance durability.
