If you order these, order a size larger than your official measured shoe size. When I did get the right size I was sadly disappointed in the so called 'memory foam' insole. Most manufacturers have chosen to use memory foam in sandals for the insole. It is NOT A GOOD IDEA because the foam just goes flat when you walk on it and since the out soles are most always made of a hard rubber or similar material, your feet are left with no cushion at all. If you are satisfied with hard sole shoes then these will be alright for you but not for my feet, I want comfort for walking. Life's too short and I don't want to do any harm to my feet with hard sole shoes. I have a pair of $25.00 sandals that have a cushion rubber insole and they are MUCH more comfortable than these. Wish I could find them again, I'd buy 6 more pair.
