Shoe stores that specialize in repairing shoes and boots can eliminate wrinkles by thermoforming. Do-it-yourself needs to buy a shoe pin as shown in the figure, which is also called a shoe brace, a shoe brace and a shoe last (there are men's and women's shoes and high and low heels):

Maintenance points:

Dust with a dry brush, put the shoe support into heat setting (you can use a hair dryer, pay attention to a safe distance to prevent scalding the leather surface) to remove wrinkles;

Brush stains and polished parts with special copper wire brush;

Cleaning cotton cloth with a small amount of white vinegar to wipe oil stains and nitrate stains, or with a small amount of alcohol to wipe oil stains, or with a small amount of 100 white gasoline to wipe oil stains is particularly strong;

Wet the vamp with a wet sponge. In order to deal with water-soluble substances, spray suede cleaner, brush it repeatedly with a rubber brush and sponge it dry. Dry it slightly and brush it in the same direction with a rubber brush to let the hair spread out;

After drying in the shade, put the newspaper in the shoe and spray the renewal agent (brightening agent) on the upper. You can also use frosted powder to decorate parts of different colors. Black must use black renewal agent (brightening agent);

Dry thoroughly and brush with a rubber brush, and the color will be more consistent.
