1) Push the stretcher into the shoe as far as it can go.
2) Turn the stretcher clockwise until it becomes snug, then turn it 2 more times.
3) Let sit for 8 hours, then it should be done.
If still tight, repeat the procedure again.
Tips:
If your shoes are leather, you'll have greater success.
Purchase shoes at the end of the day, or after work or playing sports, for best fit.
Measure both feet, as no two feet are the same size. Purchase shoes for the larger foot.
Walk around the store to ensure a comfortable fit before buying, and always try on shoes with the socks or hosiery with which you will wear them.
Warning:
Don't plan on shoes stretching with wear. If they aren't comfortable, don't buy them.
