I only did two short (~5-6 days each) tours last summer, and that was the only footwear I took. They were so comfortable that I didn't feel the need to have a "comfy" pair of shoes or sandals to put on at the end of the day. I don't think I would hesitate to use these on longer tours, though.

On previous trips, I have always used cycling shoes with recessed spd cleats that doubled as hikers and carried some lightweight sandals for each night.
