It’s wide for natural stability, thin for natural feedback, and flexible for natural movement.

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. Fit, Feel, Flex: For natural stability, natural sensory feedback and natural strength.
