The weather in Hawaii isn't always like in the postcards--rain can sweep in an instant. For like 15 minutes. Then it goes back to being like in the postcards. For constantly changing weather you need some insurance, and you've got it with the Olukai Pumehana Hulu WP Shoe. Comfortable and casual, these shoes have a durable nubuck leather upper that keeps out any water that might come your way, a Wet Grip Rubber outsole to keep your traction in wet conditions, and a soft wool lining to keep your feet cozy on chilly days.
