Summarize this article in one sentence.
Not only will standing straight and tall boost your confidence while wearing stilettos, but it will also help counter-balance your weight. This is important because wearing stilettos pushes your center of gravity forward. If you pitch your weight forward, you'll put stress on the balls of your feet. This can cause back or knee pain. Position your feet so the heels touch the ground first, then the balls of your feet, followed by your toes. Try to arch your feet slightly as they hit the ground to keep your feet positioned in the shoes. Keep practicing to get into a heel-to-toe rhythm. It's okay if you have to slow down a little in stilettos. Walking slower can make you appear more confident. If you're used to taking long strides, make the effort to shorten your steps. This will support you in an upright position and make it easier to walk heel to toe. You'll probably also need to walk a little slower as you focus on your steps. Heels automatically shorten your stride, so you'll have to get used to shorter steps. Instead of locking your knees and gripping your thighs as you walk in stilettos, try to keep your joints loose. Don't be afraid to sway your hips a little since this will help you balance and glide through your feet. If you find that you're wobbly or your stilettos hit the ground very hard, you need to loosen up more so your joints don't stiffen up. Ensure that you're not looking down and focusing on your feet as you walk. Look up and choose a point in the distance. Then visualize walking in a straight line to that point. Focusing on where you're going instead of how your feet are looking will also make you feel more confident.

Summary:
Stand up straight. Place your feet from heel to toe. Take small steps when you walk. Relax your hips and knees so they're not stiff as you walk. Imagine walking in an invisible straight line.
