What sets OluKai insoles apart from others on the market?

It all comes back to our Wet Sand Principle. Every pair of footwear (including slippers) is designed to capture the feeling of a barefoot stepping into wet sand. All at once, it cups the heel, fills the arch, and splays the toes—molding to the foot regardless of the shape. The cupped heel offers stability and shock absorption. The anatomically correct arch and contoured footbed provide all-day comfort. And the toe box allows the toes to spread naturally with no restrictions.
