I purchased these sandals in the beginning of summer and they have to be one of the most comfortable flip flop sandals I have had in a very long time. The souls are soft and as you walk in them  you kinda feel like you are walking on a cloud. The rubber is really smooth and doesn't hurt the in between part of my toes nor does it pinch or scratch the top or sides of my feet. I LOVE THESE SANDALS! In fact, I am going to purchase another pair.
