Did you know that very few of us (only 25% in one study) wear shoes that are the right size? One of the reasons: Our feet change size, expanding in both width and length, as we age. That means that the size you wore when you were 30 is probably not the same as the size you need when you are older. Check your shoe size every few years, and buy the right-sized shoes. You’ll be taking better care of your feet!
