I purchased one 2 pack of these socks about a month ago and liked the so much the I purchased more of them.  I used to get these kind of socks from Penny's, except they had an elastic top on them that when your legs swelled in the heat they would be tight.  Florsheim solved that problem and the socks are great.  The wash up well and do not shrink.  Hopefully Florsheim continues making them if I should need more.  Most companies today quit making things that are nice or work like the advertisements claim.
