Before use, apply the stretching spray to the area of the shoe to be treated: it softens and prepares the leather, making stretching easier. Choose the size corresponding to the shoe and insert the form into the footwear, with the toe well positioned and the two half-forms closed. If you need to work on a specific spot, apply the bunion plug on the correct side, right or left, at the area to be widened. If you are working on one shoe only, use the corresponding adapter to adjust the form to the right or left shoe. Turn the large screw gradually until you feel slight tension, without forcing, as excessive stretching could damage the material. Leave the shoe under tension for several hours, then loosen the screw and remove the form. Try on the shoe and, if necessary, repeat the operation, increasing the stretch a little at a time. On delicate materials, such as thin leather, patent leather or fabrics, we recommend proceeding with particular care.
