How to Check Fit
Vivobarefoot intentionally fits on the larger side—allowing toes to splay naturally. You’ve likely got the right size if you can easily fit a thumb between your child’s longest toe and the front of the shoe. As feet grow and toes splay, sizes may increase over time.
You can return unused shoes within 365 days for a full refund or store credit. No stress—just the right fit!
