I just return from raft in Costa Rica and the h2 work really well . they seem to fit big as I generally wear a size 13 Nike or New Balance -lrb- sometimes wide width -rrb- and my foot fit a little loosely into the size 12 . the sandal give great traction and provide solid protection around the toe . as any sport sandal , they do not give much stability for hike , but this sandal be probably one of the best for rafting , walk , sailing , etc. .
