Love my Teva's for fair weather hiking. My feet get dirty, but I don't mind. I bring along a pair or two of socks for when I go to sleep. Or, if its a bit chillier out there, I wear my Columbia boots. I got them on sale, and they are performing well. Had them for about 2 or 3 years, well broken in, yet not so much wear and tear considering the amount of use they have had, including rock climbing.
