I have size 13 wide feet. I wear these every day for work, in shoes and work boots.  Standard sized socks of mine such as Gold toes or Hanes have all developed holes in the toes or heals and pretty much fail catastrophically.  These from Dockers, have yet to blow out.  (We are now talking about having a set of socks running for a year or more, with zero ... zero blow outs or holes!!!) I really like these socks.  None have blown out!  YEA!  Other commenters have said that they are tight, and I believe them.  However, with my size 13EE feet, they are 10x the value of any of the size 6-13 or 6-12 socks that you can normally find in stores.  I bought some to try them.  Update:  I bought some more.  Update:  None have blown out, I am going to buy some more for some relatives and few more to make sure I have a 2-week supply on hand.  I still like them.
