VivoBarefoot Primus Lite Knit Women's Barefoot Trainers (EU 37) - Obsidian Black

Zero-drop, 3mm sole, and a foot-shaped toe box—the Primus Lite Knit brings you as close to barefoot as possible while still protecting you from the ground. The recycled PET knit upper hugs your foot in breathable comfort, and the PRO5 puncture-resistant layer lets you move confidently on any urban terrain.
