Chaco sandals, because they produce even cooler tan lines than Teva.  Actually it's because they have a very supportive Vibram rubber sole, are very comfy, dry very quickly, and allow my feet to dry out after a day of wet-foot portaging.  If I tripped other than summer, I would have an old pair of sneakers instead.  Note, I don't change into my camp shoes until tents are up, bear bags hung, firewood gathered, and usually dinner is already cooked, so I minimize the chances of my unprotected toes getting crushed, stabbed, cut, etc.
