I wear men's size 12-13, I took 12 and it turned out to be too big (long and very wide). I chose these for the thicker sole and felt more structured, but the shoe is made of neoprene like other water shoes.
Pros
Fashionable and practical: fluorescent veneer color, football-like design, reflecting the fashionable sports style. The unique five-toe design conforms to your toes with plenty of room for comfort. It can also protect your feet from sharp objects.
