Trail-ready barefoot freedom for young adventurers.
The Vivobarefoot Primus Trail Knit FG Juniors Barefoot Shoes – Eclipse are built to keep kids confidently moving over mixed and rugged terrain. Lightweight, breathable and ultra-flexible, they’re designed to let growing feet move, strengthen and feel the ground naturally – from bush trails and rocky paths to the playground and beyond.
Why kids love them
- Super lightweight, zero drop design lets feet move naturally and stays comfy all day long.
- Breathable knit upper helps keep feet cool and comfortable during active adventures.
- Barefoot feel gives a close-to-the-ground connection for balance, agility and confidence on the trail.
Firm Ground (FG) outsole for real adventures
The Firm Ground outsole is made for grippy performance on hard, dry and mixed terrain. Aggressive yet low-profile lugs provide traction on dirt tracks, rocks and roots while keeping the ride flexible and natural.
- Multi-directional lugs for reliable grip on uphills, downhills and uneven surfaces.
- Thin, flexible sole that still protects from sharp objects while allowing natural foot movement.
- Durable rubber compound built to handle rough-and-tumble outdoor play.
Made for growing, moving feet
- Wide, foot-shaped fit so toes can splay naturally and balance can develop properly.
- Flexible construction encourages natural strength, coordination and sensory feedback.
- Secure, easy-on design helps kids get them on and off quickly and stay locked-in while they move.
Perfect for
- Trail running and off-road adventures
- Hiking with the family and weekend exploring
- Outdoor play, park sessions and everyday wear for active kids
If you’re looking for kids trail shoes that prioritise natural movement, protection and grip, the Vivobarefoot Primus Trail Knit FG Juniors in Eclipse are a versatile, adventure-ready choice.

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!
