Sometimes you rip the trail, and sometimes the trail rips you. While the T Flex Power Blades at the heart of Louis Garneau's T Flex LS 100 Men's Shoes are primarily designed to punch it on blistering XC rides, those same blades can also be ripped out for a little controlled flex and a lot of additional ventilation. Speed is important, but so is comfort especially while trekking across the parking lot or during a recovery spin on a hot summer day. While the T Flex Power Blades are installed, though, the soles are race stiff. The soles themselves are nylon, though, so that stiffness doesn't come at the cost of punishing your feet with unchecked trail noise. Instead, the punishment all goes into the poor fools or unlucky friends trying to hold your wheel on the trail.
