Topo MTN Racer 4 – New updated trail shoe for technical terrain

When the terrain becomes technical, the surface unpredictable, and running demands both precision and comfort, then Topo Athletic MTN Racer 4 steps forward as a well-crafted solution for runners who want to feel secure without losing contact with the ground. The fourth generation of the MTN Racer builds on what has made the model popular among trail runners but now comes with clear improvements in both material choice and feel.

This is a shoe designed for those who run in varied and technically demanding environments – from mountain trails to roots, boulders, and steep downhill runs. Here, there are no compromises. The MTN Racer 4 delivers both power and control, making it possible to keep pushing the body even when the ground resists.

Technical terrain requires technical performance

Under the foot, we find a new version of the Vibram® Megagrip outsole, which provides even better grip on both wet rocks, loose stones, and muddy sections. The pattern is aggressive but smartly placed to maximize contact area without losing flexibility. This gives a confident step even where other shoes slip.

At the same time, the shoe is built with an updated ZipFoam™ midsole, which not only provides better shock absorption but also a more distinct push-off. The combination of comfort and responsiveness makes the MTN Racer 4 work just as well on long distances in the mountains as on shorter, intense intervals in hilly terrain. The stack height is 33 mm in the heel and 28 mm in the forefoot, with a 5 mm drop – a profile that offers both protection and ground feel.

This is how the MTN Racer 4 differs from its predecessor

For those who have run in the MTN Racer 3, several updates in the four will be noticed immediately.

• New ZipFoam™ material: The MTN Racer 4 uses a new version of Topo's ZipFoam™, which gives a softer feel at footstrike but with increased spring in the push-off. This makes every step more lively, especially when the pace picks up or during long downhill runs.

• Improved fit: The upper is constructed with a new type of mesh, which provides both better ventilation and a more adaptive fit over the midfoot. At the same time, the structure around the heel and ankle has been improved to minimize slipping – something that is clearly noticeable in technical sections where the foot must stay stable.

• Lower weight – more speed: Although the shoe has become more cushioned, it weighs slightly less than the MTN Racer 3. This gives a lighter feel in the step without compromising protection or durability.

• The outsole lasts longer: The new Vibram® sole not only grips better – it also resists wear more effectively. For those who run a lot on rocky surfaces, this means more miles before the grip starts to fail.

The overall feeling is that the MTN Racer 4 is a more mature, refined shoe – built to handle more, fit better, and feel more fun to run in.

Natural running without compromising on protection

One of Topo’s most recognizable features is the toe box. MTN Racer 4 continues with a

anatomically designed toe box, which means the toes have room to spread and work naturally. It may seem like a small detail, but it makes a big difference on long runs in technical terrain – especially when the foot swells or balance is tested on rocky fields and steep sections.

Despite this spaciousness, the shoe is never loose. The midfoot fits securely, and the heel counter provides clear support without pressure. The combination of stability, cushioning, and freedom of movement gives a running feel that is both secure and natural – something that becomes especially clear when the ground slopes or the pace changes.

When does the MTN Racer 4 fit best?

The MTN Racer 4 shines when running on hilly trails, mountain sections, technical forest paths, or mountain terrain. It is especially suitable when the surface is varied and both grip and stability need to be top-notch – but where you don’t want to lose the light, natural feel that makes running fun and dynamic.

This is a shoe for you who:

• Runs longer distances on trails, mountains, and technical terrain.

• Wants a shoe with clear ground contact, but without compromising on protection and comfort.

• Needs a stable midfoot and heel, but still values freedom of movement for the toes.

• Seeks reliable grip even on wet or uneven surfaces.

Whether you run ultratrail in the mountains, train for your next race, or go out for daily forest runs, the MTN Racer 4 will provide security, responsiveness, and performance.

A shoe that meets the demands of the terrain – and yours

Topo Athletic MTN Racer 4 is not a revolution – it is a consistent, smart development of an already beloved model. For those who need a trail shoe that can handle tough environments, adapt to your movements, and endure long distances without losing the feel – this is a strong option.

With improved grip, longer lifespan, better fit, and a more vibrant stride, the MTN Racer 4 is a choice that deserves a place at the front of the shoe shelf. Or even better – on the trail, where it belongs.
