The Ventilator won our Best Buy award because it gives you just so much shoe for $100 or less. At $135, the Moab GTX is bumped up into a slightly less value category and competes with our Editor's Choice winner, the Keen Targhee II Mid which offers a little more support, protection and slightly more comfort. The Moab dries faster and breathes better in hot weather but the Targhee II is a slightly higher performer overall. The Moab GTX is more waterproof than the Ventilator.
To get a better sense of how the Moab Mid GORE-TEX stacks up against the competition, look at a more complete review of the Merrell Moab Ventilator as well as our Hiking Boots Review.
