My son and I now have 7 pairs of the OluKai Ohana sandals in different colors..........they are the most comfortable footwear either of us has ever worn.  I've had reconstructive surgery on one of my feet, and I have a hard time finding shoes that I can walk in for very long.  Well, I can walk in the Ohana sandals all day long!  I walked all over a Florid theme park for 2 days and did remarkably well.  They truly feel like you're standing or walking in wet sand. Simply dreamy footwear :) They do tend to run a bit big.......I generally wear a 7.5 - 8, but in these sandals, I wear a size 7.
