I bought my first pair of OluKai Ohana a month ago..I thought I would try another style. This style is much better fit for my foot. I have sciotica and Planters Facilitis at times and these are SO comfortable I actually prefer these to the Ohana's. I am still trying the Ohana's but I think the arch support is not right for me. These Kulapa Kai's are great! I bought an 8M and the fit was perfect.
Second review...yes they are comfortable but the quality SUCKS. The sole separated from the upper sole within 3 months and I used them alternatively with 2 other pair...never worn outside... the sythetic (undisclosed what it is) foot pad sole that is glued I believe also comes apart and when you are a little sweaty or maybe your feet are just a little wet after drying off from the shower the sandals give off a stinky rubber foot smell...gawd awful. I would never buy this brand again. Unable to return due to living out of the country and too expensive...I am going Vionic...or Cobb Hill...comfortable and good quality.
