The Primus III is for kids who already know their own minds — and feet. So keep them grounded, but set them free. Building on the same ultra-lightweight design and flexible, grippy sole of our bestselling barefoot kids' trainer, made from recycled, animal-free materials. Now engineered with a new tongue construction for a wider opening, letting kids pull these everyday sneakers on and off by themselves. With a Velcro fastening for independent dressing and a snug, sporty fit that keeps out the "bits", but lets all the feeling in, making sure feet grip, balance and flex as close to barefoot as possible.
CONNECTION AND FEELING IN THE UN-SNEAKER SNEAKER
- Sock-like collar for snug fit with a sporty look elastic toggle fastening.
- Minimal interference in natural, healthy movement for everyday wear and sports.
- Our ultra-thin, puncture-resistant sole means they don't mold around one kids feet, so they can be safely passed on and re-loved.
KIDS MULTI TERRAIN OUTSOLE
The Kids Multi-terrain Sole is designed for ultimate flexibility, toe protection and ground feel for fast growing feet. The 2mm base and 2mm sticky rubber hexagon design allows for wild feet to feel the ground and move naturally.
RECYCLED MATERIALS
Made from recycled materials, reusing post-consumer plastic waste, helping to reduce our waste to landfill.
NO INSOLE
This footwear contains no insole, keeping you grounded and even closer to barefoot.
Our Size Guide is here to help! Vivobarefoot fit 'big' deliberately – we call this ‘the rule of thumb’. Your toes need wiggle room! This is especially important for running. If you can fit your thumb in-between the end of your toe and the front of the shoe, you’ve more than likely found your ideal size.
**After some time with Vivobarefoot shoes, your shoe size may need to increase, as your toes splay out more naturally.**
