VivoBarefoot Primus Trail Flow Men's Trail Running Shoes

Meet the Primus Trail Flow, a natural off-road performer. This streamlined shoe provides both exceptional grip and responsive ground feel to move mindfully across a variety of terrains. The durable, breathable 100% recycled polyester mesh upper keeps those agile feet cool and secure with engineered, anti-slip lacing.

Recycled Mesh Upper

Lightweight and breathable, the Primus Trail Flow features a recycled mesh upper for optimum comfort and a fresh wearing experience when running. This ultra-lightweight upper allows feet to bend and flex comfortably and naturally, whilst keeping them fresh so you can enjoy even the more intense sessions. Strategic perforations provide a constant supply of cool air to your feet, replacing hot, muggy air when you're undergoing tough periods of your run. The seamless design has no overlays, providing you with a stripped-back, comfortable upper that remains lightweight and also prevents excessive discomfort from chafing or irritation. Finally, the lacing system provides feet with a super secure fit, preventing in-shoe slipping from occurring and keeping feet secure when enduring long miles.

ETPU Midsole

The Primus Trail Flow features an innovative midsole compound made from low-density ETPU, which has been engineered to keep you connected with the ground below. Additionally, this midsole design ensures that all your muscles are engaged and your body feels strong when taking on tough runs. Helping to reduce injuries or discomfort without sacrificing proprioception, the ETPU has shock-absorbing properties to keep legs and feet fresh.

Trail Flow All-Terrain Outsole

Adorning the outsole is a lightweight Trail Flow All-Terrain outsole, which provides outstanding, reliable grip. Backed by ambassador feedback across a range of terrain, the thin sole provides outstanding grip and traction, with a reduced slip thanks to the durable lug design. The sole features deep grooves alongside a 1.8mm added height, strategically placed in areas that require higher traction, keeping you stable in all conditions. Iconic to VivoBarefoot, the shoes have a lower-profile base, keeping you closer to the ground for a more natural, barefoot feel. The sole allows the thousands of nerve endings in each foot to provide the brain with the sensory feedback it needs to move with skill. This unique design also ensures flexibility underfoot, allowing your muscles and tendons to work and recoil, allowing your foot to get stronger for a more natural spring in your step. The outsole ensures natural stability, natural sensory feedback and natural strength for the perfect in-shoe trail experience.
