Topo says:
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.
Our Verdict
Topo’s high-cushioned midsoles and roomy toe boxes are well established, and the MTN Racer 4 keeps that formula while refining several key areas. I’ve been using these as my go-to summer hiking shoe and recently completed the Esk Valley Way in them. With over 100 miles logged, they’ve held up well across mixed terrain.
The updated fit is noticeably more secure through the midfoot and heel, without losing the forefoot space that makes Topo stand out. The 33 mm ZipFoam midsole feels cushioned but stable, offering good protection without becoming soft or unsteady. The new FKT insole adds a touch more rebound and helps the shoe dry quickly after wet crossings or rain.
Breathability is excellent in warm conditions, and the upper has proved durable so far, with no signs of early wear. Grip remains consistent thanks to the Vibram Megagrip outsole, which performs well on everything from wet rock to loose trail, and even after 100 miles, it isn’t showing as much wear as I’d expect.
If you’re after a stable, cushioned trail shoe for long days on technical ground, the MTN Racer 4 is a well-rounded and capable option.
