The MTN Racer 3 is a high-performance trail shoe built for speed on rough terrain.  With a 5mm heel to toe drop and an increased 33 x 28 mm platform for even more cushioning and protection underfoot, this new update features a high-quality midsole upgraded with the new ZipFoam™ formula which delivers a softer and more energetic ride than its predecessor. The Vibram Megagrip outsole offers the reliable traction and stability we know and love about Topo shoes. Exploring rocky terrain high in the Sierra, lace up your MTN racers.
