Trail Runner Review: Salomon GCS Pro

Be cool in fastpacking's finest footwear

Why: After hundreds of miles of ultralight hiking and trail running, our testers agree that these are the most stable lightweight low-tops we've seen. The secret is Salomon's new Ground Control System, a funky mechanical innovation that repositions the cushion under your heel with every step. Four floating springs absorb shock with each heel strike-a welcome benefit on high-mileage days. But the springs also flex sideways to handle indirect impact, like the kind you get when the edge of your shoe lands on the corner of a rock. Add a wide and very grippy sole, and you get a shoe that rarely lands awkwardly-a boon to hikers and runners with weak ankles or poor balance. Testers also raved about the supportive plastic exoskeleton and one-pull lacing, which together provide an extremely secure, close fit.

Who: The shoes fit all but the flattest, widest, and highest-volume feet. Women's model is the Comp.
