*sizing is approximate.
While we say One Size, our socks do have an actual size. Our women's socks are sized at 9-11. This translates to a shoe size of 5-10 (. Men's socks are sized 10-12, 8-12.5 shoe. However, given the stretch in our socks, we can accommodate slightly bigger feet. For men, this can mean up to a 13.5 (maybe 14) shoe. Our Colombian socks have the most stretch, followed by our French socks and Japaneses socks.
Honestly, the best way to know if they fit is to try them. If you think our socks might not fit (or you know they don't), let us know and we will take care of you.
Our Youth socks come in 3 sizes: Baby (12-24 Months) / Toddler (2-4) / Kids (6-8)
