GROW UP WILD, GROW UP STRONG
BUILT FOR ALL DAY AND OUTDOOR PLAY
The Primus III is for kids who are getting to know know their own minds — and feet. 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, these everyday sneakers are easy to pull on and off. With a Velcro fastening for 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.
MULTI-TERRAIN: Giving you grip and ground feel on everything from wet and dry, rocky and firm terrain.
FIT, FEEL, FLEX: For natural stability, natural sensory feedback and natural strength.
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.**
