I wanted to make sure I was ordering the right size. So I googled how to know your shoe size. I found a cool site that showed you how to measure your feet. Stand on plain piece of paper. Fully stand on that foot and trace around. Do same with other foot. Use a tape measure to measure from longest toe to back of heel. Do both feet cause they may not be same. Then, wrap the tape measure around the width of your foot going around from area where a bunion may be to widest part by your baby toe. I did that and found my size. They fit!
