A skate shoe to which a replacement runner may be rapidly, removably coupled. No manual manipulation of locking devices is required. A first end of the runner is pivotally coupled to the shoe's base via a slot and pin arrangement. The second end of the runner is then pivoted into snap-locking engagement with a locking mechanism in the base of the skate shoe. Finger pressure on the lock mechanism serves to unlatch the runner; and, a spring drives the runner outward from its engagement with the shoe base.
