I'm wondering how Merrell Superlight boots would hold up, off-trail and in sometimes wet terrain. And the Merrell Superlight is certainly one of 'em. I've worn the Superlight and like it quite a bit. The only caveat is that a few readers have complained Merrell's lacing system results in some pinching and even abrasion around the instep.
All feet are different, so just about any boot is apt to rub a few folks in the wrong place.
Still, if you decide on the Superlights you'll want to put on a pair in the store and spend a few minutes in them, then wear them around the house for a few more hours to make sure no seams are digging into your skin. Any of these will be more than adequate for short or even long backpacking trips, yet will be light and comfortable enough even for day hikes. The one you select ought to be the one that fits you the best.
