Donna's gone next-level comfy! (Literally,we added an elevated layer of new Soft Top Foam in the midsole for the most cushiony,high-rebound bounce ever and a slightly lifted look.) But,wait,there's more. Ultralightweight and breezy uppers made from premium,100% hemp are guaranteed to keep your feet (and the planet) happy,while that classic,casual Donna style has been refined a touch for extra smiles.
