“Temperature and humidity” that cause mold

Boots and leather shoes must be careful of temperature and humidity. Mold grows when the temperature is between 20°C and 30°C. Also, pay attention to humidity. Storing wet leather shoes on rainy days when the humidity is over 80% creates a situation where mold can grow.

Dirt that causes mold

Dust and dirt on shoes can also cause mold. Even if you can’t see it, dust and dirt adhere to the used leather shoes and boots. Dust and dirt also serve as nutrients for the growth of mold, which causes mold to grow on boots and leather shoes. Also, the cream you use for care will be a favorite nutrient for mold. Mildew requires diligent cleaning of the entire shoe and the inside.

Depending on the type of mold that grows on your boots and shoes, you may not be able to remove it yourself. Treat according to the type of mold.

“White mold” that can remove mold

It is “white mold” and “green mold” that can deal with moldy shoes. The characteristic of white mold looks like fluffy dust. It is a mold that is easy to grow in buildings and food. The characteristic of green mold is a green mold that looks a little whitish. It is a mold that can be seen when mold occurs in food such as bread and fruits. Mildew and green mold are also likely to occur in damp, damp places.

Leave the removal of red mold and black mold to the professionals

Unlike white mold and green mold, “red mold” and “black mold” are difficult to remove by yourself. Mildew and green mold can often be treated because they have not penetrated the inside of the shoe, but red and black mold may have penetrated into the shoe. In some cases, mold remains and cannot be completely removed, so take it to a specialty shop such as a shoe cleaning shop.

Prevention of mold on boots and leather shoes

It is necessary to prevent mold before it grows, rather than taking care of it after mold has grown. Let’s see what kind of mold prevention measures are available.

Prevention of mold (1) Remove dirt

To prevent mold, the first step is to remove dirt. The used shoes have dirt such as dust on them. Make a habit of brushing your shoes after every use.

Prevention of mold (2) Storage after drying

After using your shoes, don’t put them back in the clog box immediately and let them dry. If you put them back in the clog box, the sweat on the inside of the shoes is one of the causes of mold growth. The key is to let it dry for a day or two before storing it.

Prevention of mold ③Ventilation once a month

Even if your shoes are dry, the accumulation of moisture in the clog box can cause mold to grow. Ventilate the shoe cupboard at least once a month by opening the door of the shoe cupboard. During times of high humidity, such as the rainy season, it is a good idea to use a dehumidifier to prevent humidity.

Prevention of mold ④Keep the storage area clean

Dust also feeds mold, so it is necessary to clean it regularly and keep it clean. It is also recommended that you change the storage location according to the season and store it in a place that does not trap moisture.

Prevention of mold (5) Frequency of use of boots and leather shoes

By reducing the frequency of use of boots and leather shoes, it leads to the prevention of mold. Rotate between frequently used shoes, infrequently used shoes, and infrequently used shoes. The reason your favorite shoes wear out so quickly is because the damage accumulates with frequent use. In order to use it for a long time, it is recommended to use it once every two days.


In order to prevent mold from growing on your valuable boots and leather shoes, daily care is required. Please try the basic care method and what to do when mold has grown.
