All available shoe repair shops are supported by machines, and shoe repair shops generally have this service. It's best to put a wet newspaper in your shoes, or cover your shoes with a wet towel, and then wedge them overnight. You can choose to blow the shoe tube with a hair dryer for about 20 minutes, usually once or more than three times every half hour, so that according to the principle of thermal expansion and cold contraction, the shoes will be bigger, and then remember to stick a hemostatic patch when wearing shoes, so that your feet will not be rubbed.
