End of life
The Revivo Take Back program is our initiative to extend the lifetime of our shoes and keep them out of landfill. Customers in the UK, US and Europe can send us your worn Vivos for free. Sorry global Barefooters, we’re working on expanding free shipping for our Take Back program to more regions, and eventually, make this available worldwide.
Reclaim your raw potential
Wide, thin, and flexible to elevate every workout
We're on a mission to create a fully circular shoe – a new Vivo made from an old one, which can in turn be made into another. The Primus 3.5 is a big step forward on this journey.
With an already mechanically recyclable outsole, the challenge is making an upper from 100% polyester, which can be recycled. The new Primus Lite 3.5 upper takes us from 43% to 81% polyester, of which 94% is recycled. Why not 100%? Because some parts of the upper still need extra durability that polyester can't yet provide. We’re working with our partners to figure out this final piece of the puzzle.
Fit, Feel, Flex
For natural stability, natural sensory feedback and natural strength.
PRIMUS OUTSOLE
The Primus Outsole is a light and thin 2mm performance outsole that's designed to put as little as possible between your feet and the ground. The side wall profile is as low as it can be, giving it a slightly lower profile towards the heel, and the sole subtly overlaps the toe — offering enough protection for urban environments, without compromising natural movement. Strong geometric shapes lead to strong feet, so the tread pattern uses our signature hexagonal design to help multidirectional flexibility and grip.
