These socks are in a junior's size but I took a chance that they would stretch over my muscle-y adult calves.  They stretched just enough to be able to still tell that it was the bat symbol and not just a yellow blob with a cape.  :)  They came just in time for me to put them on and then go stand in line to see Batman Rises - lots of compliments and odd looks - Just what I was looking for.  Unrelated to the sock purchase-  I have since broken my leg but look forward to wearing them again once I am all healed ;-) Good Buy.
