These are very nice quality socks.I think they will last for a long time. But I think they run a bit small as well. I wear a size 12 shoe and ordered these in the 13-15 size and they are still somewhat snug on my feet. I am looking for something oversized to just wear around the house ( my feet get very cold ). I have a pair I bought in 1983 when I went in the Navy and am getting tired of patching them together and would love to find another pair of nice oversized socks to replace them.
