I was pleasantly surprised with the quality compared with the picture. I thought the rubber would be alot thinner. These are substantial as the other reviewer posted. I did not find that they ran big but rather small. The width are fine but from the bottom of the foot to the top is narrow. The top rubs on the top of my foot. They are a little heavy to wear for a lengthy time. I am returning these and buying a pair of Muck boots- they are more comfortable.
