Technical trails don’t stand a chance with the Topo Athletic MTN Racer 3. From fast-paced runs winding through singletrack to slower treks where you can just enjoy being in nature, this trail shoe’s grippy outsole makes it so you can run confidently on almost any terrain. The new midsole material gives you plenty of cushion, pep and protection to keep you running for as long as you want at any pace. Details Upper: The upper features Topo’s signature fit—it has a roomy toe box with a secure midfoot and heel. They redesigned the MTN Racer 3 with even more room in the toe box. The lacing system really allows for a good midfoot lockdown to keep you nimble on your feet. Plus, it is compatible with the Topo Gaiter to keep rocks and debris out. Midsole: The new ZipFoam® midsole material provides the perfect balance between soft cushioning and a snappy response. Topo also added 3 mm of foam underfoot to give you more protection and cushion. Outsole: The MTN Racer 3 features a Vibram® Megagrip outsole that provides a ton of traction, grip and durability, especially in wet conditions.
