Shoe Stretchers are the quickest and most effective way to stretch real leather shoes for width to achieve perfect fit for your unique feet.  It's easy to use these shoe stretchers and work both shoes in your pair at the same time. Simply spray Shoe Stretch Spray liberally inside your shoes, insert the stretcher, screw the heel form into place, then twist the metal hook to expand. Allow the shoes to stay on the forms overnight, then remove the shoe stretchers and try your freshly stretched shoes on for fit. Repeat as needed. Our shoe stretchers come in two different sizes - small or large - covering a broad range of men's and women's shoe sizing. Each stretcher comes with an instep pad and four nubs that may be placed as needed to stretch your shoes in specific areas around the toes or on the top of the foot.
