KSO. I have had them about a year, wearing them 60% of the time. Climbed the billy goat trail, done some hiking, biking, boating, swimming, and just general out and about. No appreciable wear and tear, although I have been told that is dependant on getting the right fit. I got my sized by this guy who seemsed to be working with nothing but these shoes at City Sports in Chinatown.
My balence is better, my feet are stronger, definately glad I got them. I do like the look of the new Kamodos though.
