8 8. They slow you down.

Any heel over 3 inches changes your natural gait, forcing you to take smaller steps and slowing you down. That's one thing if you are walking around with a lot of other stilettoed women, but it's quite another if you are with a man in flat shoes. Now you're running along just trying to keep up, expending all this extra energy and probably compounding your usual baseline high-heel discomfort. That's not right and it's not to your advantage. As confident and in control as you might look when you are just standing or sitting around in a pair of high heels, it's a different story when you are teetering along in a pair of stilettos, unable to keep up and having to constantly look down to make sure you don't step on a sewer grate and break your ankle.
