I've been a fan of rainbow sandals for over 15 years, after years my favorite pair finally broke and I had to replace them. These are perfect and true to size. Rainbow sandals are always hard to break in and are pretty stiff when they are new. But so worth it after they conform to your feet. My advise is to completely wet them and bend them around, even yank on the straps, they wont break I promise. Then wear them until dry, do this a few times and they will fit like a charm. I highly recommend them!
