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 Topo's 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.
