<rant>Every time I buy socks at the store, they claim to work for size 9-12 or whatever, but then they are too small. They are clearly liars. They should really say, "fits size 9, 10, maybe 11, and 12 if you are okay with your feet being crushed.</rant>

Anyways, I bought these socks off Amazon and they fit well (I'm size ~12). I sorta doubt they'd fit a size 16, especially after a wash or two because they feel about perfect on me and I'm nowhere near 16. Perhaps I just like big socks and I cannot lie.
