2. Shining shoes with hand cream can slow down the friction of shoes.

Blowing shoes with a hair dryer can make them bigger and looser.

How to stretch your shoes:

1. Shoe repair shops can be supported by machines. Generally speaking, shoe repair shops have this service.

2. Cover your feet with a wet towel for a few minutes, then wrap a dry and soft towel around the squeezed place, knock it with a hammer a few times, and smooth the rubbed place of the shoes, so that the leather of the shoes will be soft and smooth, and the feet will not be rubbed.

3. Blow into the shoes with a hair dryer for 20 minutes each time, once every half hour and three times. This is the principle of "thermal expansion and cold contraction", which solves the problem of what to do if shoes are small.

4. 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.

5. Take a newspaper, knead it into a ball and dip it in some water (preferably vinegar). The whole ball will be immersed in water, but not too wet. Then, wrap the wet newspaper with a dollar newspaper, stuff it in a crowded place, and seal the shoes in a plastic bag. It will be all right overnight. Because ordinary shoes have certain elasticity, you can make them bigger so that they won't rub your feet.

6. When wearing shoes, put a hemostatic sticker on the heel and wear a pair of stockings outside, so you won't rub your feet. Or, before you put on your shoes, take a piece of soap (or the candle you usually use) and apply a thin layer on the part of the shoes where your feet are rubbed, so that the part will become smooth and no longer rub your feet.
