Is the dinosaur on these wool athletic socks breathing fire? Isn't that more of a dragon thing? Or maybe he is just eating an asteroid! We aren't sure what these dinosaur socks actually mean, but that doesn't make them any less cool. These unisex socks are made in the USA of 75% Turbowool (50% merino wool, 50% polypropylene), 15% nylon, and 10% spandex. The S/M will fit women's shoe sizes 6-10, while the L/XL will fit men's sizes 9-13.
