No matter if your feet are thin, medium or wide, Garneau's X-Comfort zone technology prevents numbness by extending the shoe's edges if needed. Having an internal lace system and a tight opening on the shoe's top avoids mud from sticking into the Baryum's fastening system. Get the best of both worlds with a stiff carbon outsole covered in rubber for optimal grip in any conditions. Heels and toes are protected with extra reinforcements so that you can head to the craziest trail sections with confidence.
