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 socks were useless because they just get holes and why bother with socks if you're 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.
