My Mom sent me these for my birthday and they are absolutely the BEST sandals/flip flops I have EVER worn. And I live in flip flops! The size is perfect for me (women's 7-9) and I usually wear size 7. My feet have widened out over the years because if I'm not wearing flip flops, I am barefoot. So, these fit me perfectly. It feels like I am walking on a memory foam mattress (which is a GOOD thing!). My back used to kill me, my calves would cramp if I had to walk any distance, but not with these! For the first time in YEARS, I am pain-free. I got the chocolate brown and blue ones and I love them!
