These are very comfortable sandals.  They provide position control, keeping your heal over the center of the back of the dandle, and do not constrain the front of your foot, because they have the classic thong style sandal front.  The arch and base of the sandal has good support and can be worn for hours without break-in.  The only negative that I can say is that Olukai has many very nice leather sandals with leather soles, I really wish I could buy this shoe in all leather.  The synthetic materials used in this sandal are durable and comfortable :) , but lack the style of the nice leather Olukai sandals :( .
