There is disclosed an athletic shoe that finds most efficacy with joggers. The shoe is supplied with a conventional upper and sole. The usual lacing arrangement is provided with the exception that additional lacing means is provided along both sides of the shoe whereby the counter containing heel portion of the shoe is constrained in a manner so that the heel portion of the athletic shoe is brought inward in the direction of the centerline of the shoe to effectively lock the heel portion with the front portion. The tying arrangement may be a continuation of the usual lacings or may be two separate laces, but in any event essentially locks the front and back of the shoe together. The lace arrangement extending to the counter or heel portion is positioned whereby the means is substantially parallel to a "spring" ligament as normally located in the foot.
