Vivobarefoot Primus Trail Flow Mid Mens – Obsidian

Description

Mid-cut boots in Obsidian for fast hikers and technical terrain. They weigh 262 g in EU 42 and suit wet rock, loose gravel and forest trails. The shoe provides barefoot feel on uneven ground with good stability around the ankle.

• Lightweight profile: Each shoe weighs 262 g in EU 42. The thin 1.8 mm sole base adds minimal volume. Allows fast steps on hilly trails.
• Trail Flow All Terrain outsole: The 3.5 mm tread depth ensures grip on wet, loose and rocky ground. The sole resists wear over long distances and gives stable contact on varied terrain.
• Breathable knit collar: The combination of recycled polyester and spandex keeps stones out and lets air circulate. The collar stabilises the ankle on uneven trails.
• Water-repellent synthetic upper: The ripstop texture with 95 % recycled polyester and 5 % spandex repels light rain and puddles. The material remains non-absorbent on damp ground.
• Natural foot movement: No insole and zero drop bring the foot closer to the ground. The design follows the principles of barefoot boots for men.
