It may even be annoying, almost as much as a squeaky shoe. However, unlike a squeaky sole, the clicking noise created by a heel is usually caused by the materials it is built of. The soles of women's heels and men's dress shoes are often made of hard materials. These include metal (usually steel or iron), plastic, and rubber. Heels also may have a soft material such as leather or foam underneath the hard surface to provide comfort when you walk. Heels are designed to make walking more comfortable for our feet. This is especially important since we spend a lot of time on foot, working at desks or not. By allowing your feet to relax while keeping them off the floor, heels help prevent ankle injuries and other problems related to sitting all day long. There are several reasons why heels might click. If you hear clicks when you walk down a city street, it's probably because of people who wear high heels. They tend to do this so that others will notice they're wearing something up on their legs! Clicking heels get the attention of potential mates or friends, just like a peacock's tail feathers. Some people are naturally born with pigeon toes. These are small bones located near the joints of the toe that stick out when the person is standing still.
