Vivobarefoot Primus Trail Knit FG

The Vivobarefoot Primus Trail Knit FG is built for runners who want true barefoot feedback on the trail without giving up confidence underfoot. Designed for firm ground and hardpack, it pairs a thin, grippy outsole with a flexible knit-and-sock upper that moves naturally with your foot while helping keep trail debris at bay. The ride is low-profile, agile, and proprioceptive—ideal for short-to-long trail runs, fastpacking, and hiking when you want to stay connected to the terrain and let your feet do more of the work.
