Vivobarefoot Primus Lite 3 Womens Running Shoes With a minimalist design, the Vivobarefoot Primus Lite 3 Womens Running Shoes allow your feet to move more naturally, be that when walking, running or working out. These lightweight shoes use the brand's Active sole, which is grippy and durable on hard terrains such as in urban environments. Wide for stability and flexible for more natural movement, the sole is a mere 4mm thick delivering a barefoot feel. All components are vegan - completely free from animal derivatives - and use more sustainable materials, making the Primus Lite 3 a more environmentally-friendly choice.
