TEACH THEM TO THINK OUTSIDE OF THE BOX
BUILT FOR INDEPENDENT MINDS
The Primus Ludo School is for kids who are learning to stand on their own two feet. This barefoot trainer in uniform-friendly black leather builds on our bestselling Primus School to give kids more independence. Designed with a pull-on heel tab, fixed flat elastic laces and a Velcro strap that small hands can manage by themselves. Made from soft, durable leather with a breathable lining for all-year wear. Created with autistic and neurodiverse communities front of mind.
URBAN: Stripped-back soles for barefoot living — so you're never too far from nature, even in the city.
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.**
