I bought these sandals after wearing Keen's Barbados II for two years. They were the best sandal I've ever owned, and I took them on every terrain imaginable. The Rockaway seems to have the same
sole, with a leather strap and top. Mere days after they arrived, I wore them to a music festival in the middle of a farm, where they met dust, mud, water, and tall grass. I have to say they performed admirably, though I find myself worrying about the leather. I'm also more hesitant to completely submerge these sandals in water, like I did with the barbados. But they are extremely comfortable, and look very good. I fully expect to get a few years out of them.
