Let them move the way nature intended in the Vivobarefoot Primus Sport IV Kids – Deep Ocean. Lightweight, flexible and foot-shaped, these barefoot trainers help growing feet stay strong and agile from the playground to the trails.
Natural Movement for Active Kids
The Primus Sport IV is built around Vivobarefoot’s foot-shaped, zero-drop design so kids can run, jump and climb with natural balance and stability. A super-flexible sole lets their feet bend and splay, encouraging healthy development and better ground feel with every step.
Breathable, Easy-On Design
A breathable mesh upper helps keep busy feet cool and comfortable all day. Smaller sizes feature simple Velcro straps for fuss-free on-and-off, while larger sizes use an easy slip-on design with a clever tongue so older kids can get ready on their own.
Key Features
- Barefoot construction: Thin, flexible sole for natural movement and sensory feedback.
- Foot-shaped fit: Wide toe box to let little toes spread and grip.
- Breathable mesh upper: Helps reduce heat and sweat for all-day comfort.

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.
