While most people are guilty of wearing shoes that are either too big or too small at some point in their lives, they do not realize the negative affect this can have on their feet in the long term. The importance of proper shoe size increases with age as your bones and muscles weaken and, quite often, falls become inevitable.
Research has shown that 3 out of every 4 individuals are actually wearing shoes that are at least ½ a size off, whether it is bigger or smaller, from their correct foot size. This greatly increases the risk of foot, ankle, leg, and even lower back pain, as well as other various foot problems.
If you are not sure if you are wearing the proper shoe size or not, ask your Podiatrist to measure your foot for the correct size next time you see him. Ideally, you want to have your feet measured by a trained shoe-fitting professional every time you buy a new pair of shoes, but in the very least, you should have your feet measured twice a year to be sure you are wearing the proper size footwear.
