VivoBarefoot Primus Trail 3.5 FG Men's Trail Running Shoes

Hit the trail to rewild yourself and reconnect with nature. The Primus Trail 3.5 FG is a light, durable, flexible trail running shoe that brings us one step closer to circular footwear.

Mesh Upper

The upper has been crafted from an ultra lightweight and breathable mesh, it allows fresh air to flow in and built up heat and vapour to escape with ease. It is lightweight so it won't hold you back and is made with recycled materials. The new upper takes it from 34% to 76% polyester, of which 93% is recycled. A quick-lacing system works with the upper to lock in the fit, allowing you to adjust with ease, as well as making on/off as easy as slipping on and off.

Ortholite Performance Insole

Underfoot resides an Ortholite Performance insole, it provides gentle support underfoot whilst preserving flex and minimalism for greater ground feel, natural underfoot flexion and sensory feedback. It is made of 98% recycled polyurethane foam, which helps reduce waste and the use of virgin plastics.

Firm Ground Outsole

Developed to provide traction over rocky trails and landscapes the Primus Trail has been constructed using a durable firm ground outsole. The outsole has been specially designed to provide durability and traction whilst still providing a barefoot feeling. The Firm Ground sole is Vivo's off-road all-rounder for exploring natural terrains. It is made with a strong, non-marking rubber compound for sticky grip and high abrasion-resistance when you need it most. With a 3mm base and 2.5mm lug height, plus a textured arch for zonal grip (ideal for technical trail movement), this sole will keep your feet firmly planted on multiple terrains - wet to dry, concrete to rocky.
