Hands down the most comfortable sandals I own. It feels like you're walking on a thick gel insole. Material is strong, but stretchy and soft. Highly recommend. Ive had no issues whatsoever with rubbing on the back of my heels, or my pinky toe (common problem with me and shoes). Great with jeans, dresses, casual to work to cocktails and everything in-between. (I bought a size 9B for reference.)
