Whether we're heading out on an all-day gravel grinder or toeing the line at our local cross-country race, the PEARL iZUMi Expedition Mountain Bike Shoe strikes the perfect balance of all-day comfort and power transfer. Thanks to the breathable perforated upper, our feet stay fresh even as we pick up the pace, and the BOA L6 closure lets us lock in a secure fit. The nylon composite sole is paired with an EVA heel insert for pedaling efficiency and off-the-bike stability with extra vibration damping, so we don't have to worry about foot fatigue on epic rides.
