Always put fun within reach
Ready for non-stop play all day
No sticky little feet in the Primus Sport IV, thanks to its breathable mesh upper that's light and airy. Yet the Velcro closure ensures a snug fit, making these ideal for everyday wear for your bundle of curiosity. Let them roam free and play in any environment on a multi-terrain outsole, pulling this versatile barefootwear on and off all by themselves with the handy heel webbing as they go.
Urban: Stripped-back soles for barefoot living — so you're never too far from nature, even in the city.
Fit, Feel, Flex: For natural stability, natural sensory feedback and natural strength.
Vivobarefoot Kids Size Chart
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.
You can return unused shoes within 365 days for a full refund or store credit. No stress—just the right fit!
