How to Keep Climbing Shoes from Smelling?

Climbing shoes are an essential piece of equipment for any climber, but they can also be a source of unpleasant odors.
The combination of sweat, bacteria, and the closed-toe design of climbing shoes can make them a breeding ground for bad smells. However, there are a few simple steps you can take to prevent and eliminate odors in your climbing shoes.
Causes of Odor in Climbing Shoes
Climbing shoes are designed to fit snugly on the foot, which means that they don’t allow for much air circulation. When your feet sweat, the moisture can become trapped inside the shoe, creating an ideal environment for bacteria to thrive.
This is the main cause of odors in climbing shoes. Climbing shoes can develop odor due to various factors, including:
Perspiration: Climbing is a physically demanding activity that can cause your feet to sweat profusely. The moisture created by sweat provides an ideal environment for bacteria and fungi to grow, leading to unpleasant odors.
Bacteria and Fungi: The combination of warmth, moisture, and darkness inside climbing shoes creates a breeding ground for bacteria and fungi. These microorganisms thrive in such conditions and can produce foul-smelling odors as they break down sweat and skin cells.
Poor Air Circulation: Climbing shoes are designed to fit snugly around your feet, which often means limited air circulation. Insufficient airflow traps moisture and odor inside the shoes, making it difficult for them to dry out and exacerbating the problem.
Improper Drying: If climbing shoes are not adequately dried between uses, any residual moisture inside the shoes can promote bacterial and fungal growth. Storing your shoes in a damp environment or packing them in a closed bag can also contribute to the problem.
Inadequate Foot Hygiene: Neglecting proper foot hygiene, such as not washing your feet regularly or wearing dirty socks, can contribute to the development of odor in climbing shoes. Bacteria and fungi can transfer from your feet to the shoes, leading to unpleasant smells.
Climbing Environment: The nature of climbing often involves contact with dirt, mud, rocks, and other organic matter. These elements can cling to the outsoles and uppers of climbing shoes, providing a breeding ground for odor-causing bacteria and fungi.
Prevention Methods
The best way to deal with odor in climbing shoes is to prevent it from happening in the first place. Here are a few tips to keep your shoes fresh and smelling clean:
Proper ventilation: Make sure your climbing shoes are well-ventilated to allow for air circulation. Avoid storing them in sealed plastic bags or containers that don’t allow air to circulate.
Use shoe inserts: Using a shoe insert made of a moisture-wicking material can help to keep your feet dry, which in turn can prevent the growth of bacteria.
Keep shoes clean: Wipe the inside and outside of your shoes with a damp cloth or a specialized shoe cleaner after each use.
Allow shoes to dry completely: Before storing your climbing shoes, make sure they are completely dry. If you need to dry them quickly, stuff them with newspaper or a towel to absorb the moisture.
Cleaning Methods
If you already have an odor in your climbing shoes, there are several ways to clean them and eliminate the smell:

Baking soda: Sprinkle a little baking soda inside each shoe and leave it overnight. The baking soda will absorb the odor and can be easily shaken out the next day.
Vinegar: Mix equal parts water and white vinegar in a spray bottle, and then spray the inside of the shoes. Leave them to dry completely before wearing them again.
Specialized shoe deodorizers: There are several commercial shoe deodorizers available that can help to eliminate odors. Look for products that contain enzymes, which can break down the bacteria causing the smell.
Maintenance Tips
To keep your climbing shoes smelling fresh, it’s important to maintain them properly. Here are a few tips to follow:
Air them out: After each use, take the time to air out your shoes. Leave them in a well-ventilated area to dry, and avoid storing them in sealed containers or plastic bags.
Store them in a dry place: Make sure your climbing shoes are stored in a cool, dry place. Avoid storing them in damp or humid areas, as this can encourage the growth of bacteria.
Use odor-eliminating products: Consider using odor-eliminating products, such as shoe inserts or sprays, to keep your shoes smelling fresh and clean.
