The Primus Lite 3.5 is a versatile performance trainer for running, cross-training, and dynamic day-to-day living that reclaims your natural potential. It’s wide for natural stability, thin for natural feedback, and flexible for natural movement.
The upper is made from 81% recycled polyester. We currently need the polyurethane for durability, but the Primus Lite 3.5 upper is closer to 100% polyester than ever: one step closer to a circular upper, and one step closer to circular footwear.
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.**
