imo I hike with Tevas (unless I am doing a lot of boulder/mountain climbing, than I switch to my boots with ankle support) and I love them. I don't mind my feet getting dirty, I can wade through water with ease and they dry quickly. I do, however, wear wool socks to bed. For two reasons really, 1. to keep my sleeping bag/hammock/tent/sleeping pad clean, and 2. because it feels great!

In the summer season I will wear my Campmor zip pants. They allow a lot of breathing and can get wet and dry quickly. But at night I bring along my pants to sleep in. An extra pair of boxers and one pair of wool socks aforementioned.
