The Primal Zen is a minimalist shoe that comes with some added cushion and a more grounded base. Its newly designed outsole guarantees that ultra-light fit and feel you've come to love in the Primal 2, yet adds a bit more protection with its platform that naturally wraps the shape of the foot. Featuring a soft suede upper with perforations throughout, the Primal Zen Suede is an ultra comfortable, highly breathable option.
