I also saw an idea on the internet before: you can rub some white wine or white vinegar on your feet, then knead it with your hands a few times and slowly soften it. After a night, you can wear it the next day. I think this method is relatively simple.
Another way is to take a newspaper, knead it into a ball and dip it in some water, but don't get the whole paper wet. Then wrap the wet newspaper with a dollar newspaper and stuff it in the crowded part, and then seal the shoes in plastic bags for the night.
Or you can apply lubricating oil or soap to the place where your shoes wipe your feet. Fish-mouth shoes usually rub their feet where their toes are exposed. Just use a shoe expander for one night. In addition, find an oily thing such as soap, soap or candle, and apply a thin layer on the part that contacts the heel most. Finally, slowly wipe off the wax ash on the surface, so that the treated shoes are smooth and will not rub their feet again.
The most important thing is to choose the right shoes. Choosing the right shoes is definitely more important than whether you can wear them. You can buy a slightly bigger and softer heel. But some shoes are too big to fall out, especially boat shoes without straps. You can also take a pair of flat shoes with you and change them when you are tired of wearing high heels in the office.
Although wearing high heels will make you look taller, don't be too perfectionist, so how can others live? More importantly, make yourself more comfortable and don't wear high heels easily on unnecessary occasions.
