The Vivobarefoot Primus Sport IV Toddlers Stone is designed for little adventurers who need lightweight, breathable barefoot sneakers for all-day play. Built on a wide, foot-shaped last with a thin, flexible sole, it helps support natural foot development, balance and coordination from the very first steps.
Key Features
- Barefoot design: Thin, flexible sole encourages natural movement, helping toes splay, grip and feel the ground.
- Foot-shaped fit: Wide toe box gives growing feet room to spread and strengthen without restriction.
- Breathable upper: Lightweight mesh helps keep small feet cool and comfortable during active days.
- Easy on and off: Simple strap-and-elastic closure makes it quick for kids (and parents) to get shoes on and off.
- Lightweight build: Minimal bulk so little legs don’t tire as they run, jump and explore.
- Vegan-friendly materials*: Made with performance synthetics and textiles. (*Check size/colour for final material details.)

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!
