Real Work Wear 6 pack Men's Tube Sock (Sizes 13-15) 8719
Product Review (submitted on May 22, 2013):
I actually purchased socks from 3 different companies when I bought these because the place I had been buying from quit stocking the large sizes. Of all the socks I bought, these fit over my calf and were thicker than the others. So, as long as these are available here, I will be buying my socks here.
