I picked these up after I got nothing but blisters from the Chacos I tried first. Huge improvement. They're comfortable with and without socks. I prefer wearing them with socks if I don't foresee wet conditions though, because they can get pretty stinky.
After getting wet, they drain within seconds and dry completely within an hour or two. They're surprisingly comfortable when wet, though I got a little tired of walking in wet shoes after they got wet, dried, and then got wet again in the same day. But I like the full coverage and the grippy tread.
I also really like the aesthetics of these shoes--so much better than any of the other water shoes on the market.
