Everybody knows that carbon fiber is the ideal material for lightweight power delivery in an outsole. It isn't known, however, for its comfort. With the Louis Garneau T Flex 2LS shoe, howev er, you can have the power and the comfort at the same time. T flex technology provides the best of both worlds with a stiff, responsive, carbon fiber sole. This sole, however, has flex built in, so walking becomes much more comfortable than with a traditional carbon fiber sole. The flex is located strategically, however, so it doesn't give up any of the outsole's power transfer. The T Flex 2LS also features dual density lugs for increased traction off the bike. Closure is handled by the BOA system, which allows you to precisely fine tune your fit. The uppers are made with ultra breathable microfiber to keep your feet cool during the ride.
