Here, I will teach you a few tips to help ease the pain of grinding new shoes.
1. Cover the ground shoes with a wet towel for a few minutes, then wrap the crushed feet with a dry soft towel, and knock them with a hammer several times to smooth the ground shoes, so that the skin of the shoes will be soft and smooth and the feet will not be ground.
2. Take a newspaper, knead it into a ball, dip it in some water, not too wet, but the whole ball should be soaked in water, then wrap the wet newspaper with a dollar newspaper, stuff it in the crowded part, and then seal the shoes in a plastic bag for the night.
3. If the new shoes pinch your feet because they are too small, you may wish to cover them with a wet towel and support them with a shoe wedge, so that they will fit your feet.
4. Before putting on your shoes, take a piece of soap (or the candle you usually use) and apply a thin layer on the part that contacts the heel most, so that the heel will become smooth and no longer rub your feet.
