Our shoes are currently only offered in women's sizes 5 - 12.That being said, we do have a number of men who fit in them and wear them! For men's sizing, you would typically want to size up 1.5 sizes from your men's size. (If you wear a 10.5 in men's, you should be able to fit into an 12 in women's sizing. Keep in mind they may have a narrower fit then a men's shoe.)We hope to expand into larger sizing in the future. Stay tuned!
