A fan favorite for race day and daily training, the Topo Athletic MTN Racer 4 offers rugged performance on technical trails. A 33 x 28 mm platform delivers underfoot cushioning and a protective barrier between you and the ground. Our new upper is fine-tuned for performance on technical terrain.
The MTN Racer 4 now features our FKT insole, allowing for faster water drainage and added rebound, while our improved gaiter attachment system keeps out debris. The Vibram® Megagrip outsole provides reliable traction and durability, delivering serious performance when the trails get gritty. Compatible with our Switchback Gaiter. (MTN Racer = Mountain Racer)
