Topo Athletic Trail Picks: Mountain Racer 3 and Terra Venture 4 Waterproof
Two trail-ready Topo Athletic shoes: a faster, better-protected Mountain Racer 3 and a waterproof Terra Venture 4 built for wet day hikes and dog walking.
Introduction
Topo Athletic’s trail line has built a loyal following for good reason: roomy toe boxes, locked-in midfoots, and a ground feel that few cushioned trail shoes manage. Two models stand out depending on how you use the trail, and both arrive with sensible pricing.
Topo Athletic Mountain Racer 3
The Mountain Racer 3 keeps the fit fans loved: locked in through the midfoot and heel with the classic wide Topo toe box. The headline update is more protection and cushioning underfoot without a weight penalty. Rather than add a rock plate, Topo raised the stack by three millimeters to a 33 to 28 millimeter midsole, preserving the trail feel and nimble ride that made the original appealing.
The new ZipFoam is the same softer, lighter, bouncier compound used in the Ultra Venture 3. The proven Vibram MegaGrip outsole carries over, delivering strong traction with good wet-weather resistance. The tightly woven durable mesh upper keeps dirt and debris out, still breathes well, drains quickly after water crossings, and holds up to abrasion.

It weighs 10.1 ounces in a men’s nine, a slight increase from the previous version’s 10.0 ounces, but still light for a well-protected shoe. It comes in two colorways each for men and women, retails for $150, and ships in June.
Tongue Security and Fit Details
One small but frequently praised detail: two loops at the base of the tongue anchor it over the top of the foot so it does not slide around while running. Combined with the secure lace-day system, the shoe stays planted even on technical descents.

Topo Athletic Terra Venture 4 Waterproof
The Terra Venture is Topo’s do-it-all outdoor shoe. Cushioning sits lower than the Ultra Venture or Mountain Racer, so it suits shorter-distance running and hiking. Most users gravitate to it for runs up to around 15 miles, choosing the higher-stack models for ultra distances. The platform is a 25 to 22 millimeter stack with a three millimeter drop, and a forefoot rock plate adds protection on technical trail.
A full-length Vibram MegaGrip outsole makes it a convincing crossover from hiking to trail running. The upper mixes durable abrasion-resistant mesh in the forefoot with a more open breathable mesh in the rear foot for better drainage and airflow. It retails for $135 and also lands in June.

Who the Terra Venture 4 Waterproof Suits
Coming in August at $150, the Terra Venture 4 Waterproof replaces the Hydro Venture entirely. It uses a bootie construction rather than a laminate, the same approach Topo applies to its boots, which holds water out over the life of the product. The setup mirrors the Hydro Venture’s three-millimeter drop, so fans of that shoe will feel at home.
While long-distance runners and through hikers generally prefer non-waterproof shoes, this is a strong pick for day hikes, wet weather, snow, or simply keeping feet dry and insulated outdoors. It even doubles as a comfortable everyday wet-weather shoe.

Buying Advice
If you run longer distances or want a protected shoe that still moves fast on technical trail, the Mountain Racer 3 at $150 is the stronger pick. If your trail time splits between shorter runs and hikes, or you need a reliable waterproof option for wet conditions, the Terra Venture line covers both, with the Terra Venture 4 Waterproof arriving in August at $150 and the standard Terra Venture 4 at $135.
Conclusion
Both shoes reflect what Topo Athletic does well: a comfortable, roomy fit, tuned cushioning for the intended use, and serious Vibram traction. Match the shoe to your distances and weather, and either choice is easy to live with.
