The Olukai Men's Nui Casual Sandals are one of Olukais most comfortable designs yet, the Nui combines exceptional midsole cushioning, top-grade leathers and island craftsmanship for a one-of-a-kind sandal experience. The straps attach to the outer edges of the sandal which is great for wider feet. The anatomically correct footbed gives your feet support and comfort. Once you slip into the Nui sandal from Olukai, it's easy to see where the sandal got its name. Translated from Hawaiian, Nui means "greatest," and this sandal could easily be the greatest flip-flop you've ever owned.
