I am hard on socks.  I used to be a Gold Toe business socks fans years ago.  Then I tried these socks 1 1/2 years ago.  I bought 12 of them.  They have lasted until now.  I am the kind of person who runs out into the gargare or down the sideawalk in my socks.  I know I should put shoes on but I don't.  I did try several other brands a few years ago but they didn't fit right or holes soon developed.  As you know you can't mend holes.  These socks fit right and cushion my feet.  I wish I could say some thing bad about these socks but I can't.  Also, I like all my socks black as they go with anything and makes washing them a much simpler task.  I highly recommend these socks.
