This version of the Primal Zen features a soft suede upper with perforations throughout, making it an ultra comfortable, highly breathable option. 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. Product Details If you’re already a fan of the Primal 2, then consider the Primal Zen its heir apparent. 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. The Primal Zen's slick construction also includes an attached tongue that won't fall out of position, and slightly stretchy laces to give you the perfect fit across the top of your foot. The cork footbed guarantees your feet will stay cool and comfortable, with or without socks. With so much comfort designed into this shoe, you'll truly feel like you're wearing nothing at all!
