The best I've ever owned!
These things work great on rock either dry or wet. I spent 4 days fly fishing on a river wearing these sandals and am SO happy with their performance. They stick on wet rock like you can't believe! The buckle did start to annoy me a bit but not enough for me to want to remove them. The strap adjustment system is well designed and works great.
I recommend these sandals to anyone wanting a sandal that can perform in many different conditions.
