Squeaky shoes may be caused by friction between the shoe’s insoles and bottom. Try sprinkling baby or talcum powder underneath the inner sole. If the insoles aren’t removable, you can use the powder along the insoles’ seams. If your shoes squeak on slick surfaces, such as wood floors, the problem will most likely go away once you wear them outside a few times and the rougher surface scuffs them up. The bottoms of the shoes won’t be as polished and smooth, so they’ll be less likely to squeak. To speed up the process, you can also rub sandpaper on the sole. Wet shoes may also squeak, so it’s important to dry out your shoes if they get wet. First, remove the soles or inserts and allow them to air dry separately. You can also stuff them with balled-up newspaper to absorb the moisture. Never put wet shoes in the dryer or under a heater, as that can damage them.
