Review: I really like this shoe. I use it for fairly aggressive trails, including larger rocks, steep slopes, logs/branches across trails. I will be running these in the upcoming USMC Mud Run, so I will update after that....the true test.
This shoe has lots of lateral support for uneven terrain, a very nice gel sole (as the name suggests) and good overall support without being bulky or cumbersome.
Review: I like this shoe and I would recommend it for your more aggressive trails. It features a Performance Trail Outsole, which means that it has a rock plate in the forfoot, reversed lugs and sticky rubber for traction, for a more protected, efficient ride. It has the stability of the 2140 trail and a Performance Trail Upper, water resistant, more durable, breathable and gusset construction to prevent debris from entering the shoe.
Recommended for: Serious trail runners looking for a stable and protective shoe for aggressive trails.
