You'll get noisy shoes because they don't fit properly, especially if you're wearing them barefoot or haven't worn them in yet, according to Cleary. To soften leather heels, dampen the inside and outside of the shoes with room temperature water. Wear them until they are completely dry. This will prevent squeaks. Heels can also be squeaky if there is a hole in the bottom of one. This allows air to come into the shoe, causing a noise when you walk. Fill the holes with wood putty to fix this problem. If your heel sliders aren't working, try lubricating them with oil or shaving cream. Don't use nail polish as it will harden over time. Heels can also be squeaky if you have flat feet. If you wear shoes that have a high arch support, such as sneakers or hiking boots, you can get away with having flat feet since you're not putting any weight on the arches of your foot. However, if you plan to wear heels regularly, then you should get diagnosed with plantar fasciitis or some other foot issue before you start walking in heels every day. Heels can also be squeaky if you have narrow toes. If your nails are long enough to touch when you squeeze your toes together, then you have enough room for your nails to rub against each other when you walk.
