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.
