I can't provide a full review, as I ended up returning them before actually hiking in them, however, I will say that the reason why I returned them is because they were much more heavier and "chunkier" than I had expected.  I had read that this was a lightweight hiking shoe with good arch support.  I ordered a 7, 1/2 size up for room for either heavier socks or hotter days/longer hikes with swollen feet.  These felt so heavy and clunky on my feet, it made me feel like I was walking different.  Not exactly what I was looking for, but hoping to find a Merrell that I will like.
