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.

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.
