Bought this in the coral color for my daughter. Normally Keen sandals need to go up a 1/2 size, but thanks to other reviewers suggestions,  I ordered her normal size. The fit was perfect and the color is wonderful. She loves flip flops, but had to start wearing orthotics. The molded footbed of these give the needed support with the benefit of cupped heels to keep the heel lined up correctly in the sandal.  The comfort and stability is priceless when you want to avoid injuries while enjoying the minimalist comfort of flip flops.
They rinse off easily when they need cleaning. If they are anything like the (multiple) Keens that I own they will hold up for many miles. More expensive than normal flip flops and worth every penny.
