The fan-favorite Topo Athletic MTN Racer 4 is an exceptional trail running multi-tool with unsurpassed versatility, durability, and technical terrain capability.
Don't be deceived by the "Racer" name — even Topo Athletic will openly tell you that the MTN Racer 4 isn't a pure racing shoe. But DO believe that it's absolutely one of the best trail running shoes in the game. With the versatility for consistent daily miles, long runs, and fast paces over gnarly paths, it can do it all.
If you loved v3, you'll be happy to know that v4 retains the same excellent midsole and outsole setup. Its tuned ZipFoam cushioning delivers a lighter and more responsive ride than earlier formulations. And the high-stacked geometry delivers the ideal balance of cushioned underfoot protection and simple speedy agility. Further, we can trust that the rugged and durable outsole retains the legendary slick-surface traction of Vibram Megagrip rubber.
Crucially, the engineered mesh upper is now a slightly snugger fit throughout its entire length. Of course, the classic Topo fit principles still apply: a roomy toe box with a secure midfoot and heel. Now, the upper fit will provide even better security on technical trails. To cap it all off, we've been gifted with an improved gaiter attachment system and a truly premium FKT insole. Made of beaded closed-cell TPU, this insole is non-absorbent for faster drainage and is dramatically more cushioned and responsive directly underfoot.
Altogether, take on any trail run with confidence — choose the quiver-killer Topo Athletic MTN Racer 4 and experience the difference yourself!

MIDSOLE
- ZipFoam is an upgraded EVA blend that continues to evolve to be lighter and more responsive than earlier versions. It offers an ideal balance of resilient performance with the right measure of cushioned and protective comfort.
- FKT insole is Topo's special sockliner of bouncy TPU foam. This beaded closed-cell foam type is non-absorbent to resist water accumulation and pamper your feet with extra cushiony responsiveness.
OUTSOLE
- Vibram Megagrip provides industry-leading grip on variable surfaces and especially on wet rock sections. Deep and durable lugs deliver ultimate utility across technical terrain.
UPPER
- Engineered mesh incorporates recycled materials and creates a slightly snugger fit throughout for improved performance on technically-demanding landscapes. Topo's signature fit always pairs a roomy toe box with a secure midfoot and heel.
- Improved gaiter system now features a more universal hook-and-loop attachment at the heel, plus the standard D-ring at the tongue base.
