Womens Primus Trail FG 3.5 Shoes

Built for runners who chase the trail long after the road ends, the Women's Vivobarefoot Primus Trail 3.5 FG is made to move naturally across wild, uneven terrain. Light, flexible and impressively durable, it’s designed to let you run free over rocky paths, hard-packed ground, and everything in between.

 

This latest evolution takes a meaningful step toward circular design. Created with high-performance, vegan materials, the Primus Trail 3.5 FG features an upper now made from 76% polyester, 93% of which is recycled, moving significantly closer to a fully recyclable construction. With an already mechanically recyclable outsole, it represents real progress on the journey to creating a shoe that can one day be remade again and again.

 

Underfoot, the Firm Ground outsole uses a sticky rubber compound for dependable grip and long-lasting durability. A 3mm base with 2.5mm lugs and a textured arch provides zonal traction and stability, giving you confidence across wet, dry, firm, and rocky terrain. You stay connected to the earth beneath you, without sacrificing protection.

 

The foot-shaped fit allows your toes to splay naturally for improved balance and a stable base of support. A thin, flexible sole enhances ground feel, activating the thousands of nerve endings in your feet to deliver the sensory feedback your body needs to move with precision and control. By allowing muscles and tendons to load and recoil naturally, it supports stronger, more resilient feet over time.

Light on your feet yet tough on the trail, the Primus Trail 3.5 FG invites you to rewild your run and reconnect with nature.
