DESCRIPTION:

The Primus Lite 3.5 is our original training all-rounder, reimagined with a new upper to get us closer to circularity. Made for moving naturally and building natural strength during runs and wide-ranging training disciplines, it’s perfect for experienced barefoot cross-trainers and those new to barefoot performance.

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 puzzle piece.
