While high heels may complete your outfit, they may not always be the best choice for your back. High heels can cause back pain. High heels force your body weight to shift forward and creates poor posture. This causes pressure in your lower back in the lumbar region and can lead to muscle restraint and pain. High heels also provide minimal shock absorption. This means that the impact of you walking on your spine is more severe compared to walking in sneakers or another flat shoe. If you experience any back pain associated with wearing high heels, it may be best to reduce the amount of times you wear them.
