Overall these are really comfortable socks; i am size 10.5 and they fit me very well.  I was concerned b/c 6-12.5 seemed a like a large range to cover.  the socks arrived on time and with always they was no issue with amazon shipping/order/deliver/etc.  so far the socks stay up well, but they are only a couple months old so I will post again if there is issue down the road.  wish there was more color in the 'argyle' pack.  two browns and one argyle is the only negative I have about the transaction.
