TEACH THEM TO THINK OUTSIDE OF THE BOX
BUILT FOR INDEPENDENT MINDS
The Primus Ludo School is for kids who are learning to stand on their own two feet. This barefoot trainer in uniform-friendly black leather builds on our bestselling Primus School to give kids more independence. Designed with a tongue rather than a sock collar for an adjustable fit that feels snug on narrow and wide feet, plus fixed flat elastic laces and a Velcro strap to help kids pull them on and off easily. Made from soft, durable leather with a breathable lining for all-year wear. Created with autistic and neurodiverse communities front of mind.
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!
