Great shoe.  I do a 3-5 mile hike every day walking the dog (Treeing Walker Coonhound as if that adds relevance).  Comfort and the ability to handle the rough terrain, basically rough loose gravel, are my requirements.  I've been a long time users of Merrell (and Keen) footwear so I had high expectations for these.

Sizing is pretty spot on.  I ordered a half-size up from my normal to account for the heavier socks I wear.  I'm a normal width with a high instep, these felt comfortable right out of the box.  The sole is stiff /  thick enough I don't feel the protrusions of the stones while the tread is stable enough my foot won't roll.  Surprisingly light, I've put a couple of 5  milers in on some blisteringly hot days without fatigue or any soreness.

I'll be interested in seeing how they stack up, longevity wise, to some of my more expensive footwear that have endured the countless miles.
