Salomon S/LAB Genesis 2: two weeks on the trails, with the mountains in sight
A few strides around a shop rarely tell you much about a trail shoe. So we took the Salomon S/LAB Genesis 2 out for two weeks, on a variety of trails and in the mountains, mainly in dry conditions. Our first impressions are very positive: this latest version puts stability and protection at the heart of its design for technical terrain.
Some shoes are chosen for a specific session; others are the ones you consider taking when the route promises to change character. A narrowing path, a steepening slope, then the mountains taking over: it was across this varied terrain that we got to know the S/LAB Genesis 2.
After two weeks, our assessment is very positive. This remains an initial period of testing, however: long enough to move beyond out-of-the-box impressions, but too short to judge its performance over several hundred kilometres or in an ultra.
An update focused on footing
The S/LAB Genesis 2 retains a clear mountain focus. Salomon has reworked its platform and outsole, claiming a 39% increase in ground contact area. That figure describes a change in construction; it does not, of course, mean an equivalent increase in grip.
The new Contagrip lug geometry, combined with the activeCHASSIS, aims to improve traction and stability. The shoe has a 6 mm drop, 4.5 mm lugs and a claimed weight of 272 g per shoe.
These choices give a clear sense of its intended use: supporting runners when the terrain demands more careful foot placement. The value of this construction becomes apparent less on a perfectly smooth straight stretch than through changes in pace and terrain.
From everyday trails to the mountains
The benefit of these two weeks was precisely the opportunity to vary the terrain. Testing only on smooth paths would have overlooked an important part of the Genesis’s intended use. Equally, using it exclusively in the mountains would have told us less about its place in everyday runs.
Our very positive assessment therefore reflects this mix of trail and mountain running. It leaves us keen to extend the test, particularly as conditions become more demanding.
One point should remain clear: our runs took place mainly on dry ground. We therefore cannot draw firm conclusions about wet rock, slippery roots or deep mud. Grip depends too much on the surface and conditions to generalise from a single setting.
Built for the trails
The upper uses Matryx Micro fabric, which Salomon describes as lighter, durable and breathable. The internal EndoFit sleeve is designed for a precise fit, while Quicklace allows one-pull adjustment. A small integrated gaiter and a protective toe cap complete the protection. Cushioning comes from optiFOAM² foam.
Beyond the technical names, these features address practical concerns: keeping debris out, protecting the foot and maintaining a secure fit when running over uneven ground.
Trying the shoe on remains essential. A model can offer every feature you are looking for and still be the wrong match for your foot shape. Take time to check the space in the toe box and how securely the shoe holds your foot, keeping descents in mind as much as those first few strides.
Our verdict after two weeks
The S/LAB Genesis 2 impressed us during this initial testing period on trails and in the mountains. Its technical focus makes it an interesting option for runners whose routes regularly venture beyond easy paths.
Two weeks are enough for this favourable first assessment, but not yet to establish its durability or comfort over a full day of running. Further outings will allow us to explore those aspects.
For now, one thing is certain: we want to keep running in it. And take it onto some more demanding trails.
