You know the feeling when you get a flat tire on your bike? The same gut-wrenching emotion wells up when you get a heel lift in your boot on the first day riding. We spend endless hours on hill and in the STI Lab developing tech so that you won’t get this feeling. The Lock Boa™ solves it once and for all, and with a single Boa™ reel! We threaded the Boa™ lace through our exclusive Tongue Tension System, so that as you tighten the reel, the 3-D tongue constricts around your forefoot. It’s the benefit of a dual Boa™ at the price of a single.
