The Mavic Crossmax Boa Mountain Bike Shoe is stocked with performance and comfort features for cross-country riding. The synthetic leather upper is durable and breathable, and the memory foam insole cushions our feet for comfort on long rides. The fiberglass and nylon sole provides exceptional power transfer and stiffness. TPU pads on the underside of the sole give us off-bike traction, and the 2-bolt SPD-compatible cleat ensures a secure connection.
