Thanks, but other than the occasional stress fracture from running, I've never had any foot problems at all. I can walk for up to 10 miles barefoot without problems (and have), but prefer the Chacos around town when the weather permits.

On pure aesthetics, I much prefer sandals to shoes (hot, closed leather boxes), but I don't wear them when it's not socially and climactically appropriate, and in my lifestyle, that doesn't leave nearly often enough.
