Is it necessary to wear cotton leather shoes?

Such a question must be decided by yourself. If you feel cold, you can wear cotton leather shoes. If you are not cold, there is no need. Of course, there are also regional differences. If you live in the Northeast, you must wear cotton leather shoes in winter. Otherwise, your feet will definitely get cold or even freeze. But if you are in the south, especially south of the Yangtze River, the chance of wearing cotton leather shoes is relatively small. Of course, you can generally wear second-cotton shoes, but the chance of wearing thicker cotton leather shoes is very small.
