The Topo Athletic MTN Racer 4 is your go-to trail running shoe for high performance across any terrain. While the name may hint at race-day speed, this versatile trail shoe goes well beyond racing. Designed for everything from daily miles to long runs and technical descents, the MTN Racer 4 delivers unmatched performance, agility, and comfort in rugged environments.

At the core of this trail powerhouse is Topo’s ZipFoam™ midsole, which offers a lighter, more responsive ride than previous versions. Combined with a high stack height, the cushioning delivers the ideal mix of underfoot protection and speed-friendly responsiveness. Whether you’re navigating rocky trails or pushing the pace, the MTN Racer 4 supports every step with a balanced ride. The Vibram® Megagrip outsole adds confidence on slippery, loose, or wet surfaces, thanks to its superior traction and durability.

Topo refined the engineered mesh upper for a more secure fit throughout, enhancing stability on technical trails without sacrificing breathability. You’ll still enjoy the brand’s signature roomy toe box, paired with a snug midfoot and heel for a locked-in feel. The upgraded gaiter attachment system improves compatibility, while the new FKT insole—crafted from beaded closed-cell TPU—adds even more underfoot comfort, drainage, and responsiveness.

If you’re looking for a trail running shoe that handles everything from daily training to tough ultramarathon terrain, the MTN Racer 4 brings dependable cushioning, traction, and fit in one high-performance package. Experience the trail like never before with Topo’s most versatile trail runner yet.

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.

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.
