Mens Vivobarefoot Primus Flow

The Vivobarefoot Primus Flow is built for people who want to move naturally, efficiently, and without restriction. Designed for walking, running, and training, this ultra-lightweight barefoot shoe supports your body’s natural mechanics while still offering just enough protection for modern environments. Weighing just 150g, it’s Vivobarefoot’s lightest shoe ever—so light you’ll barely notice it’s there.

When walking, the Primus Flow encourages a more natural posture and stride by allowing your feet to feel the ground beneath you. This sensory feedback helps improve balance, foot strength, and awareness, whether you’re commuting through the city or moving through daily life. For runners, the stripped-back design promotes efficient, midfoot-focused movement and a closer connection to the ground. The 4mm low-density ETPU midsole provides subtle cushioning to help reduce impact stress while still maintaining excellent proprioception—making it ideal for those progressing on their barefoot journey.

In training sessions, the Primus Flow truly shines. Its flexible sole and wide toe box allow your feet to splay naturally during squats, lunges, and dynamic movements, helping you build strength from the ground up. The breathable, seamless recycled mesh upper keeps your feet cool and unrestricted during high-intensity workouts, while the minimalist construction supports natural stability and control.

Whether you’re transitioning to barefoot footwear or refining your natural movement practice, the Primus Flow is designed to move with you—not against you. As with all barefoot shoes, progression is key: start slow, build strength, and let your body adapt over time.
