An in-line skate enables the wheels to follow an arc when turning, thereby offering such enhanced performance characteristics as energy return, shock absorption and reduced turning diameters. The skate comprises a flexible beam affixed to a rigid boot backbone by a single attachment position bracket. The flexible beam carries the skate wheels thereon, and is adapted to flex about its single attachment location in response to the radial force generated while turning, aligning the wheels of the skate toward the radius of the turn, making the turn easier and more energy efficient. Additionally, flexing of the beam under the load of the skater in usage will result in a spring back of the beam when the load is reduced, providing an energy return system to recover energy that would otherwise be lost during certain skating maneuvers.

[ What is claimed is:] [1.] A skate comprising:a boot for securing a skater's foot therein, the boot having a sole;a backbone frame fixedly attached to a bottom of the sole of the boot;a single attachment bracket fixedly mounted to a central portion of the backbone frame and depending therefrom;an elongated flexible beam having a front end portion, a rear end portion, and a central portion, the central portion being attached to said attachment bracket by a fixed connection with the flexible beam being oriented along a longitudinal axis of the skate boot,at least one wheel rotatably supported by a forward end of the flexible beam; andat least one wheel rotatably supported by a rearward end of the flexible beam;wherein the flexible beam is configured for preventing bending in a vertical direction relative to the backbone and while permitting the front and rear portions of the flexible beam to bend about a vertical pivot axis formed by the fixed connection in directions extending laterally with respect to said longitudinal axis in response to lateral forces imposed thereupon during turning of the skate.
