This All-Out Blaze line of Merrell shoes is great.  The shoe last is different than that of the Moab (which I got a few years ago in a half-size larger than my usual size 9M), so be aware of that.  For the All-Out Blaze Aero Sport, I got my usual 9M.  I wanted a cool and breathable but rugged shoe to wear in the summer in the Western North Carolina mountains.  Since it rains so much here, it is hopeless to try to get shoes that are waterproof, even if they claim to be breathable.  So the next best thing is to get shoes that breath and are cool, and then let the water pass right through and dry fast!  Anyway, these work great and offer a surprising amount of support and protection (from everything but sand, dirt, and dust).  The soles are very grippy, the toe box is quite roomy, and the heel counter is snug and comfortable (no blisters).  The heel lift is 4 mm, which is pretty minimal, so you really get a nice forefoot feel and comfortable toe-off when walking.  Not sure they'd be smooth enough on the inside to wear without socks.  The best part is that all the shoes in this line have the same fit, so you can order different styles and expect the same results.
