Ensure a perfect fit for growing feet with AdventureCo’s Vivobarefoot size guide for toddlers, kids, and juniors—plus tips for natural fit and return reassurance.
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.
