ABSTRACT:
This invention provides a unitary skate component extending from a blade to the sole of a skate boot. The structure has two spaced-apart walls which are vertical and substantially parallel at their lower portions and which at their upper portions curve smoothly upwardly and outwardly in opposite directions through a substantial radius to terminate in flange portions which may be attached to the boot sole. The large radius provides yieldable impact-absorbing regions without stress-concentration points.
