i ordered these for a thru hike up the AT. i had been training in merrell moab ventilators and thought these were just a waterproof version of those. WRONG! although they are similar, they are not cut the same and they are not as comfortable. i wore them out on the trail for 2 weeks but they are nowhere near as comfortable as a ventilator. look good, seem like good boots, but not as comfortable as the ventilators.
