I bought these in a 7.5 based on the size I wear in the Keen Venice sandals. Luckily, they fit my feet and look nice.  I wanted a dressy sandal that could accommodate my flat feet and bunions. I give them 4 stars because by the end of the day, the straps aggravated my bunions.  In comparison, I can wear my Venice sandals all day without any foot pain.  I got compliments on the sandals and I love the Cascade Brown color, which I would describe as  a gray-brown.
