well they are water proof no holes... but the craftmanship is horrible the lip isn't even close to the same size on either side ...in general they just seem poorly glued together
also the elastic part at the top they just sliced into the ruber basicly so it can stretch....not to good on the ankles when you put them on
kamik has much better construction for the money edit: the rubber just came apart at the seem after only 2months these shoes are not suitable to work in
