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. 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. 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. Strong, non-marking rubber compound for sticky grip and high-abrasion when you need it most. The Primus Trail Knit is an evolution of the Primus Trail FG: our original, best-selling trail-running sneaker.
