The Primal Zen is a minimalist, vegan-friendly shoe. Its unique outsole guarantees an ultra light fit and feel, yet adds a bit more protection with its platform that naturally wraps the shape of the foot. We didn’t call this shoe “Zen” for nothing. In shoes this comfortable, all of your worries will just slip away. This super minimalist, kicking-around-town shoe offers a wider outsole width than the Primal 2, and a touch more cushion while still keeping the weight off, at just 8.2 oz. Sun Ray and Graphite colorways of the Primal Zen features a soft suede upper with perforations throughout, making it an ultra comfortable, highly breathable option. These models are $10 more.
