Reclaim your raw potential
Wide, thin, and flexible to elevate every workout
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.
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.
