The heel support prevents the shoe from deforming, so it can also be used as a shoe keeper. Then adjust the length. The round swivel head can be rotated to the right to extend the length vertically. 2. If you want to expand the length of your shoe, you can adjust the width of the shoe stretcher to the smallest degree, then turn the round swivel head to the right and extend the length vertically. 3.
