Once you wear thick shoes and thick socks in winter, your feet will obviously feel stuffy and hot, which is very uncomfortable. If it's summer, you can also brush and wash the shoes and take them outside to dry. In winter, the temperature is low, and it's not easy to dry the shoes after brushing. Besides, the shoes are so thick, and the same goes for socks. Therefore, some people are too lazy to change their shoes and socks. What's more, one pair of shoes is worn all winter without changing. In this way, money seems to be saved on buying shoes, but health is often "wasted". Changing shoes and socks frequently is one of the measures to prevent tinea pedis. Generally speaking, socks should be changed once a day, especially for people with sweaty feet. Dirty shoes and socks may contain pathogenic filamentous fungi. When your feet are sweaty and your shoes and socks are damp, fungi can spread more easily. In order to prevent people who already have tinea pedis from infecting their family members, it is best to wash the patient's socks separately and often dry them in the sun. Even if there is insufficient light in winter, try to dry the socks thoroughly by air drying or drying them on a heater. Many male friends only prepare one pair of shoes in winter and wear them for a long time once they are put on. This practice needs to be changed. As long as conditions permit, you should prepare two or more pairs of shoes to wear interchangeably so that the shoes have sufficient opportunity to dry. In winter, people mainly wear warm leather shoes. Leather shoes cannot be washed, so it is necessary to change and wash the insoles as often as possible. In addition, you can go to major shopping malls to buy special shoe odor disinfectants to kill bacteria in shoes.
