Olu - "Ocean" Kai - "Comfort". The spirit of this brand is embraced in these two Hawaiian words. OluKai flip-flop, sandals and shoes provide their comfort from a combination of premium materials and contoured shapes that form the structure of OluKai. At the core of all their footwear is their anatomical footbed; a biomechanically engineered shape that supports and positions your entire foot naturally, allowing it to move through the stride comfortably and correctly. Their deep heel contour centers, aligns, and supports the foot. An extremely comfortable flip-flop that you have to try to believe!
