I bought these socks as a gift for my dad. He is very picky about how socks fit and the material they are made of. I didn't know if he would like these or not, but he loves them! He said they are very comfortable and make his shoes fit even better. He said they seem to be great quality, and expect them to last a long time. Although he thinks they will last a long time, he still wants me to order him more. Great purchase for me
