These are great hiking boots. Very good grip and extremely waterproof. As people point out, the soles are stiff, front to back. However, they are quite soft, so you definitely feel it when you step on pointy rocks. Sharp rocks also did a lot of (cosmetic, I think) damage to the side of the sole.The only complaint for me is the the heel cup seems a bit low and it rubs a bit at the top on both of my heels, something I haven't had with other boots. But it took 4 days to get any blisters from it.
Adendum: upon taking the boots out of the closet for another hike, noticed that some of the stitching on the side had busted and there now is almost an inch long split. I'll have to look into getting them returned/replaced :-( Too bad, I really like them otherwise.
