"I wear a Women's 11 and initially ordered this a size down in a 10 based on reviews. When I tried them on without socks, my toes were right at the end and rubbed up against the top when I walked, so I returned them and re-ordered in a 10.5. The half size down from my normal size was perfect for me! I don't have particularly narrow or wide feet, just average. Can't wait to wear them throughout the summer!"
