Recycled Mesh Upper Lightweight and lean, the VivoBarefoot Primus III All Weather FG offers a less shoe, less weight experience for enhanced speed and freedom to move. Following the natural shape of the foot, the recycled mesh upper encourages natural human movement flexing with the foot for as little interference as possible. The mesh allows cool air to flow throughout the upper to create a perfect microclimate for your feet to thrive in. The increase in ventilation ensures your feet remain cool, dry and comfortable at all times. The upper is specifically shaped for the foot with minimal interference to your natural movement so you always stay in control. The mesh upper has been made using water-resistant constructions and non-absorbant materials so that you can train all year round without sacrificing that barefoot feeling. This vegan-friendly shoe will deliver you with the ultimate lightweight and flexible running experience plus, it has been constructed using recycled materials. Completing the upper is a lacing system that locks down the midfoot so you can enjoy distraction-free strides. Active Outsole The outsole has been specially designed to provide durability and traction whilst still providing a barefoot feeling. The Active sole offers the most sensory underfoot experience, providing ultimate grip and durability on hard surfaces in urban environments. Low in profile, the signature 4mm thin sole puts minimum material between your feet and the ground while allowing your feet to move as nature intended.
