Kujo shoes are fitted true to size, with a slightly roomier toe box. We know buying shoes online can be a bit tricky. So, we've taken the worry out of it - if it's not just right simply exchange it for the next size, free of cost. Yep - we fully cover the shipping back to us (in the continental US), as well as the new pair shipping back out to you! For more information, see our exchanges support page.
