Bought as a Christmas present, used only 3 times in the swimming season when the tightening string on one shoe broke. This was just before a planned river trip. Teva said we would have to return the shoes for evaluation and that if warranted we would get replacements 1-3 weeks after that because we didn't purchase direct from them. They referred us to Amazon, who said tough luck. Essential component of these $70 shoes shouldn't break after 3 uses, and Teva should go out of their way to back up their (previously) well regarded product. Undependable product from don't give a crap company.
