Ways to prevent grinding feet.

1: Gently rub the upper leather with your hands to make the leather itself soft. However, you must not use excessive force to prevent the leather surface of the shoes from wrinkling.

2: Cover the place where the feet are rubbed with a wet towel to make your leather soft, and then let it dry in a cool place.

3: Apply white wine or white vinegar to the place where the feet are rubbed, moisten for 5-15 minutes, wait for the cortex to soften slightly, and then wipe it clean.
