Merrell ProMorph in the endurance test: Between Alpine trail and Berlin pavement

When you hear Merrell, many people first think of hiking boots, solidly built for forests, rocks, and everything in between. However, the brand has also been seriously tweaking its running line for some time now - with the goal of delivering performance not only off-road but also on asphalt. The new ProMorph is an exciting step forward. A hybrid shoe that promises to be able to do both: trail and road. We tried it out - in St. Moritz and Berlin. The two running worlds could hardly be more different.

The first impression

Merrell has made some major improvements with the ProMorph: lighter, more responsive, with more cushioning-but not watered down. The core element is the new FloatPro+ midsole with nitrogen (yes, it sounds chemical, but it's very comfortable to walk on). Plus, a Vibram® outsole for grip on almost anything you might find underfoot-gravel, roots, asphalt, no problem.

What immediately stands out is the midfoot fit. I have rather narrow feet, and the instep panel really makes a difference here - a shoe that doesn't slip, but rather guides you smoothly without constricting. Merrell understands that support doesn't always have to be about rigidity.

The test: St. Moritz vs. Berlin

In St. Moritz, we rode classic alpine trails-scree, climbs, everything the elevation profile offered. The shoe remained stable, with no noticeable weaknesses. Good control downhill, no weight on the foot uphill. The cushioning is noticeable, but not spongy-more of a springy feeling that doesn't diminish even after 10 kilometers.

Back in Berlin, it's back to everyday life: roads, traffic lights, quick changes of pace. This is where the real appeal of the ProMorph comes into play - you don't have to think about whether the shoe is right for the route. Just put it on and go. The transition from trail to road works surprisingly well, without feeling like you're making any compromises.

Conclusion

The ProMorph isn't a shoe for extreme conditions - it's not the lightest racer, nor the most robust mountaineering boot. But that's precisely what makes it interesting. It covers a wide range without seeming arbitrary. For people who like to decide spontaneously whether they're going through the park, over the hill, or across town today, the shoe is simply perfect.
