Cute shoes, comfy for a short time. But then came the blisters on the back of my foot! It doesn't matter if I wear these on dry ground or when out on the water, the same thing happens. (I even went to a shoe store to get my foot measured properly and was told I had the correct size shoes.) The worst of it is, Teva won't let me return them! Lesson learned: wear new shoes on carpet for a day or two before venturing outside.
