Love the colors on these sandals, and Reef is a trusted brand.  I ordered a size 9 and while they're a little snug (I'm normally a size 10 but opted for smaller because I wanted a slightly tighter fit for walking long distances and making sure they stay on my feet and don't loosen too much over time) they're perfect as they really stay on my feet and they don't cut into the tops of my feet like my old sandals.  Very happy.
