The Primus Trail Flow is a barefoot minimalist trainer: zero drop and a very thin sole give the most direct ground feel and natural gait, but need enough foot strength and an adaptation period — not for beginners directly switching from thick shoes. Build up gradually from short distances and flat terrain.

Minimalist barefoot design, no traditional midsole, thin rubber outsole with removable insole
The Vivobarefoot Primus Trail Flow (2026) is Vivobarefoot's lightweight barefoot trail runner, upholding the brand's minimalist barefoot philosophy with zero drop, a very thin sole and a wide foot-shaped design for the most natural, ground-close running experience. It uses the signature barefoot design — no traditional thick midsole, just a thin rubber outsole and removable insole — letting the feet feel the terrain directly and work naturally, with a roomy barefoot toe box for natural toe splay and stronger ground perception. Zero drop (0mm) is the core. The breathable mesh upper is light and dry. The thin rubber trail outsole grips dirt and rock on natural terrain. At about 220g and NT$5,800, it's a barefoot trail and terrain-perception trainer for advanced runners with strong feet.
