Isn't grinding shoes a quality problem?

Yes, I haven't.

The quality of a pair of shoes is not determined by grinding feet, but by the fabric and workmanship of the shoes. Many times, this has nothing to do with the quality problem at all, but there are some problems in the process of choosing the size.

New shoes will have the problem of rubbing their feet when they are just worn, and they will get bigger and bigger after wearing for a while. The fabric of shoes really rubs their feet easily, which is a quality problem. Improper wearing can also cause foot rubbing, but it is not a quality problem.

Extended data:

Grinding feet is a problem in many new shoes. It is painful to walk in these shoes, and it will also scratch your feet. To solve the problem of rubbing your feet, you can apply a towel soaked in white wine to your toes for about 10 minutes, so that your shoes will not feel like rubbing your feet.

Apply vaseline to the place where you wipe your feet and leave it for two days. During the period, vaseline will be applied continuously, so that the shoes will become soft and not rub their feet in two days. You can also knead the newspaper into a ball and dip it in water (not too wet), then wrap the wet newspaper in dry newspaper and put it in your shoes for one night.
