1. Hard soles: Cloth shoes usually adopt a relatively simple sole design, which may be harder than the soles of other shoes, which will affect the support and comfort of shoes and lead to uncomfortable wearing.
2. Shoes don't fit well enough: Cloth shoes usually don't have the design of inner height or outer height, so people who need to wear them pay more attention to the size and their foot shape when purchasing. If the shoes don't fit, the feet will slide inside the shoes and it will be uncomfortable to wear.
3. Walking for too long: If you walk or stand for a long time, even the most comfortable shoes will make people feel uncomfortable. At this time, you can choose to wear more comfortable shoes or have a proper rest.
To sum up, I feel very tired after wearing cloth shoes for a day, which may be caused by factors such as hard soles, inappropriate shoes or long walking time. If this situation persists or seriously affects daily life, I suggest you consult a doctor or buy shoes that are more suitable for you.
