I love Olukai sandals.  They are pricey but in my opinion worth it as they offer excellent support for my feet.  I decided to try out the Kulapa Kai but they just don't work out for my fat wide feet.  I couldn't push my foot all the way in so there was a space at the top and the support for my foot was in the wrong spot.  So, I will be sticking with Ohanas.  The seller, Orthotic Shop is 5 star in shipping speed and packaging.
