Welcome to Trail Shoes Reviewed. Today, we’re analyzing the Topo Athletic MTN Racer 3, a shoe that stands out for its exceptional anatomical fit and technical trail-ready features.
This review covers its specifications, fit, and performance and why we consider it one of the best anatomically fitting trail shoes on the market today.
Key Specifications of the Topo MTN Racer 3
- Weight: 286g (UK Size 9)
- Stack Height: 33mm (heel) | 28mm (forefoot) | 5mm drop
- Outsole: Vibram Megagrip with 6mm lugs for superior traction
- Midsole: ZipFoam cushioning (EVA + thermoplastic blend for cushioning and responsiveness)
- Upper: Breathable engineered mesh
- Gaiter Attachments: Three attachment points – front D-ring and two at the back for a Topo-specific gaiter
With a combination of Vibram Megagrip, 6mm lugs, and ZipFoam cushioning, this shoe is designed to handle technical terrain.
Anatomical Fit: A Unique Approach
Many brands promote a wide toe box, but Topo has gone further with the MTN Racer 3 by refining the entire foot fit:
- Snug Heel Counter: Keeps the heel and midfoot secure without excessive movement.
- Medial Arch Support: Provides midfoot stability, offering additional structure for those who need it.
- Wide Anatomical Toe Box: Allows natural toe splay, reducing pressure on the forefoot and improving comfort during long runs.
The built-in medial arch support is particularly beneficial for runners with Plantar fasciitis or Posterior tibial tendonitis, as it helps support the arch and reduces excessive strain on the plantar fascia and posterior tibial tendon. This added structure can aid in reducing foot fatigue on longer runs and provide extra stability for those who overpronate.
This rear-to-forefoot anatomical fit makes it one of the most secure and natural-fitting trail shoes available, providing stability while allowing unrestricted movement.
Performance on the Trails
With 6mm lugs and a Vibram Megagrip outsole, the MTN Racer 3 handles a variety of surfaces effectively:
- Muddy Trails – Provides consistent traction
- Technical Mountain Terrain – Secure grip on uneven surfaces
- Rocky Terrain and Wet Surfaces – Vibram Megagrip ensures confidence underfoot
The ZipFoam cushioning delivers a comfortable ride, though it lacks some of the spring and responsiveness found in high-energy return midsoles. This makes it a stable and protective shoe rather than one designed for uptempo runs.
For a trail shoe with more energy return and responsiveness, consider the Salomon Genesis.

Who Should Consider the Topo MTN Racer 3?
This shoe is well-suited for:
- Runners who need a secure, anatomical fit
- Technical trail runners requiring strong traction
- Those looking for a wide toe box with a snug heel fit
- Long-distance hikers and runners who prefer a cushioned but stable ride
- Runners with plantar fasciitis or posterior tibial tendonitis who need added midfoot support
For runners seeking more cushioning for ultra distances, the Brooks Caldera 7 may be a better choice or for mild to moderate stability the Asics GT-2000.
