A retractable and expandable telescopic member is provided at the rear of the skate including a stub shaft fixedly mounted to a heel plate to which a threaded cylinder is rotatably mounted and engages a threaded pedestal extending upwardly from the support member, and rotation of the threaded cylinder will cause retraction or contraction of the support and the blade securely mounted in the support about the rotation about the pivot pin extending through the front of the boot.
