Im selling a pair of 3M Waterproof boots that I bought last December online from Jcpenny's. The reason why im selling them is because customers mentioned in the reviews that the boots ran small so I went with the size 13. I only worn the boots once, for a few hours since I needed them for the rain but was too big and kept slipping a bit even if i wore double socks. If you wear a size 12 they will be too big since I wear a Size 12 and didnt work for me. If you are a true 13 or possibly even a Size 14, it will fit. Come try it on to make sure. It looks and feels brand new without any issues.
