Marathon Handbook tested the Salomon S/Lab Genesis 2 in Chamonix, covering UTMB trails. The shoe impressed with grip and stability, changing downhill running for the tester.

The shoe's 23 percent more ground contact and low stack provide a direct connection to the ground. It excelled on various surfaces, from dry hardpack to wet roots, enhancing confidence on steep descents. Read more trail coverage.

Despite its performance, the quicklace system was problematic, requiring frequent re-tightening. Salomon's new model, priced at $200, offers a balance of capability and cost, suitable for technical trails. Related: Rabbit Trail Gear Review: Summer Performance and Comfort.
