Where can I buy socks for mens shoe size 18?

that's a big foot, and you know what they say about big feet?? bigger sock

you can find it big and tall warehouse go online @ www.bigandtallstores.org/

Actually, most big & tall stores emphasize big, and they stop at shoe size 16. I'm just hoping that my son's feet are done growing (he's only 17.)

2bigfeet.com has socks up to size 20.
