Usually wears a size 9. My son bought a pair in Maui and was very happy with them. I bought 8 1/2 and they fit like a glove as I don't wear socks. If you plan to wear socks, please order your normal size. Go barefoot 1/2 size smaller. You are perfect. Super light. The support is really good, the construction is what you would expect from Olukai. So I give it a 10 for fit, style and comfort. Take a pair! PS I stole two pairs of thin white cotton socks from my wife. Additional incredible unicorn status. Get some Greg. Seams are still tight with no snags and tuff. Sole wear is minimal and insoles and shoes fluff well in the washing machine. Comfortable comfortable comfortable. I still wear them every day of the week on my Aloha Mix record. Buy a pair of Greg.Mahalo
