Get the Right Fit the First Time
We want to make sure you pick the perfect size when ordering online. That’s why we’ve created clear, easy-to-use size charts for every Vivobarefoot product.
Not the right fit? Changed your mind? No worries. Return your gear in unused condition within 365 days for a full refund or store credit — no fuss, no pressure.
Our Size Guide is here to help! Vivobarefoot fit 'big' deliberately – we call this ‘the rule of thumb’. Your toes need wiggle room! This is especially important for running. If you can fit your thumb in-between the end of your toe and the front of the shoe, you’ve more than likely found your ideal size.
**After some time with Vivobarefoot shoes, your shoe size may need to increase, as your toes splay out more naturally.**
