Primus Trail Knit FG Mens Graphite/Gum

The Primus Trail Knit is an evolution of the Primus Trail FG: Vivobarefoot's original, best-selling trail-running sneaker.

It features a knit upper for enhanced breathability and purer trail mobility, made with recycled materials, and a sock-like construction to keep out trail debris.

FOR TRAIL RUNNERS, RAMBLERS AND KINDRED SPIRITS

• FIRM GROUND OUTSOLE - The Firm Ground Outsole is made from a sticky rubber compound for maximum grip and durability. 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.
• ORTHOLITE INSOLE - The Active Ortholite Performance Insole is made of 98% recycled PU foam, which helps reduce waste and the use of virgin plastics.
• ANIMAL-FREE - Made from materials that are free from animal products.
• PUNCTURE RESISTANT - The Pro5 Puncture Resistant finish is a lightweight and flexible 0.8mm layer on the sole. Protective underfoot to keep painful bits out, but still letting all the feeling in.
• WEIGHT - Based on a single shoe in Men's size: EU 42 | UK 8 | US 9 - 400 g

Made for trail running, the Primus Trail Knit FG is also excellent for fastpacking and hiking. Its low profile and versatility also makes it a popular choice of outdoor lovers wherever they tread.

A knit upper and sock bring flexibility and protection. A quick-lace system means easy adjustments. And a thin Firm Ground sole balances barefoot sensation with grip, feeling fast on varied hardpack terrain, building natural strength with every step.
