Vivobarefoot Primus Trail II FG Mens

The Primus Trail II Firm Ground is Vivobarefoot's original, best-selling trail running shoe. It's light, durable and flexible for all kinds of adventures on trails that bring you closer to the earth.

Continuously improved through athlete testing and material innovation, the Primus Trail II FG has nothing more or less than exactly what you need - made with high-performance, recycled, vegan* materials.

The Primus Trail II FG is first and foremost a trail running shoe and also excels at pack-in and hiking. Its low profile even makes it popular for an outdoor-oriented urban lifestyle, including HIIT workouts and strength training.

The wide, thin, flexible construction provides maximum sensitivity and natural mobility on uneven ground. The quick lacing system makes it easy to put on and take off and easy to adjust. And the Firm Ground sole balances sensitivity, grip and speed on varied hard-packed terrain, building natural strength with every step.

FIRM GROUND OUTSOLE

Stable footing on many surfaces.

ORTHOLITE INSOLE

The active OrthoLite performance insole is made from 98% recycled polyurethane foam which helps reduce waste and the use of recycled plastics.

BREATHABLE MESH

Light and comfortable material that breathes.

STRONG RUBBER COMPOUND

Strong, non-marking rubber compound for firm grip and high wear resistance when you need it most.

VEGAN*

*The main materials in all Vivobarfoot's Vegan* products are synthetic and do not come from animals. Vivobarfoot does not (yet) have the visibility they need into the production of all the small components (such as glues and dyes) used in these products to ensure they meet vegan best practices. So while they believe the shoes are vegan, they cannot yet guarantee it and want to be completely open about this.
