I frequently buy kids/youth shoes because I have small feet and they fit better. And lets face it they're usually cheaper. I followed the sizing chart using foot measurements. Im normally a 6.5 womens and I ordered a youth size 4. They fit perfectly. I have a difficult time getting sandals because I have a high arch, and my foot is pretty narrow. My daughter recommended these, she got hers a few days ago. We are both more than pleased with the comfort and the adjustments you can make to the straps. We also got them a week sooner than expected.
