The Terra Fi's are the quintessential active sandal. The tough-as-nails spider rubber outsole grips to anything wet, dry and in between. The foot support is great, I have a high arch and the footbed cradles the foot like a baby. The strap system is very reliable, though the toe strap does pinch the little toe sometimes. Personally, I get the most use out of these in the boundary waters, where they are the perfect hybrid for fast drying after unloading and enough support for the portage. I've been wearing Terra Fi's all my life, and I probably won't stop any time soon.
