Fun fact about Einstein: he didn't wear socks. So how's that for irony - a sock printed with the iconic face of a man who shunned socks?! (Pshhh, and they say he was a genius? Kidding, Einstein, you're legit.) Apparently he thought it was pointless to bother with socks if you are already wearing shoes. If only we could travel back in time and sponsor his poor little sock-less feet, he would probably have had a different opinion. Fits women's shoe sizes 6 to 10. 63% cotton, 34% nylon, 3% lycra.
