Primus Trail FG 3.5 Mens

Primus Lite 3.5 Mens

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.
