For a woman, I have very big feet! I'm only 5'10", but my feet are size 11 women's. Due to a glitch in the system at Amazon, I would click on the women's size 11 and would receive a men's size 11. In an attempt to fix it, I would then receive a women's size 10, which was kinda too small. After going back and forth on this a few times oh, I just settled for the women's size 10. It wasn't way too small, it was just a little snug.These are really great shoes!! They have lasted me several years , and this is my second pair. My first pair is still kicking along , I wanted one that wasn't as ragged so I could wear them to church and stuff. I wear flip-flops everywhere and these are orthopedic, so they keep my feet from pronating in and my bunion from getting worse.These are really excellent shoes and the people who sell them are so accommodating in trying to make sure you get the right size!! They even paid for shipping both ways several times! I am very impressed with the company. I ended up buying two new pairs, so I could bling up one for fancy occasions. I have a bad back, so the orthopedic shoes help a lot. These shoes are so sturdy, mine have lasted almost five years, even with my son accidentally stepping on the back many times! I have even now purchased him some, which have lasted him over two years, and he's a size 16! Love these shoes!
