Technical trails have met their match with MTN Racer 3. This new update features an increased 33 x 28 mm platform for even more cushioning and protection underfoot, with improved toe sweep for a fast transition and smooth ride. The midsole gets an upgrade with our new ZipFoam formula for the perfect balance between soft cushioning and snappy response, while the Vibram Megagrip outsole you know and love is back to deliver serious traction and grip when the trails get gritty. DETAILS Ortholite: Comfortable insoles with long-term resilience and anti-microbial properties. Anatomical toe box allows toes to spread naturally and comfortably. A Vibram outsole provides unparalleled grip and traction and durability from the leaders in technical outsoles. Zip Foam: Proprietary midsole compound which is springier than EVA and offers more rebound over the life of the shoe.
