These are very comfortable sandals and they are pretty, too. The soles are not very thick, but they are not paper thin either. The insole is not completely flat and supports your foot much better than other sandals of this type. They were on sale, so I bought them in 3 colors. I have bunions, so I really can only wear thong sandals. So, when I find a comfortable and stylish sandal, I buy more than one pair.
