8/6/15:  Update.  After having these socks for a bit, they not only change the overall size after washing, but the material seems to be different.  There are two types of feel to the socks.  One is a more slick feel and the other is a cushiony, fluffy-type feel.  It is almost like they are two different types of material.  I know they are exactly all the same as when I purchased them, I tossed everything else my husband had except these.  The longer we have them, the less I like them.  I downgraded my rating from a 3 to 2 stars.

I have been looking for good quality men's socks that won't deteriorate and pill off after washing and that wash up well and keep their shape.  These socks don't lose their material and cause little black balls to fall off from them.  They hold their shape when pulling out of the dryer.  Odd thing is that they wash up different sizes.... literally.  When I match them to each other there is as much as an inch different in size.  (We purchased six packages of the same size.)  I have to pull them out to get them to match up.  They eventually are the same size but this just seems weird.  Also, the overall quality of the socks when I opened each package seemed a bit cheap.  There were small looped threads protruding everywhere.  I was a bit hesitant to keep them, but decided to try them out.  I'd say they are just ok.
