4. A ball pick sphere constructed of rubber or other material that is 40 to 50 mm in diameter 45 mm being optimal secured by set screws with a center mounting hole located below the horizontal plane of the axel mounting locations on the frame allowing the sphere to extend beyond the forward outer channels of the frame exposing the ball pick sphere surface 180 degrees both longitudinally and laterally allowing for maximum available contact surface thus allowing the skater to achieve extreme angles required for certain spins, jumps, and footwork common in figure skating while protecting the frame.
5. The ball pick sphere may be reversed when worn, simply remove the ball pick sphere from the frame flip over and re-mount.
6. In a variation of claim 4 the ball pick sphere may have varied surface configurations to enhance the properties of grip and rebound.
