I give these cascade flip flops a 5 star review. I had major surgery fusing 4 joints in my mid foot over 3 years ago and really couldn’t wear flip flops anymore. I tried a pair of these on in a store this summer, the turquoise blue ones, and fell in love with them, wearing them everywhere. The arch and heel cup are perfect, great cushion and fit my narrow foot extremely well as other flip flops are almost always to baggy in the straps. I ordered 3 more pair when I got back from my travels. When I got the other 3 pair, all size 7, the wine colored ones fit exactly like my turquoise ones but the granite grey and blue springs pairs were a little different, a little smaller and the arch was not in the right place for me. So, I’m returning those 2 pair and will go to a store that carries them where I can try them on. Hopefully, fingers crossed, I will find those same ones that fit the same as my turquoise colored and the wine colored ones because I’m afraid if I go to a size 8 they will be too loose in the straps. I love, love, LOVE the 2 pair that fit well!!
