For that dude who's toes are falling off in the bar from the plug boots he insists on wearing, give him a pair of these tongues and ask him to flex them. These are the stiffest tongue we have! We made some fro Bode Miller and decided to offer them to the world. The 12 Pro Flex Tongue is compatible with Full Tilt Original and Soul Shells. Customize your boots and get ripping. Comes as a pair.
