Got rained only once. My arches are supported and after a day of walking on concrete factory floors, my feet arent killing me. So I say, no problems here. The overall quality can be described as sturdy. La única razón que no les pongo 5 estrellas es porque el cuadrito que hace que no se salga el ajustador se quebró y cayó en ambos zapatos. Although the sandals were a bit loose they are just too comfortable. Rather than return them, I just gave them to my husband. no problems! Waste of money and time and a total hassle! the stretchy material is perfect and these are a great motivator to loose weight.
