SAEDNEWS: Shoe odor develops when sweat, moisture, and bacteria build up inside footwear. Proper cleaning, drying, and ventilation can help keep shoes fresh.
According to SAEDNEWS, feet naturally produce sweat, especially when shoes are worn for several hours. Sweat itself usually has little odor, but when moisture remains inside shoes, it creates a damp environment where odor-producing bacteria can multiply. Shoes made from materials with limited breathability may trap even more moisture.
Bacteria that live naturally on the skin can break down components of sweat and dead skin cells. During this process, they can produce compounds with an unpleasant smell. If the inside of a shoe stays warm and moist, these microorganisms can become more active, gradually making the odor more noticeable.
Wearing one pair of shoes every day may prevent the interior from drying completely. Even when the outside appears dry, moisture can remain around the insoles and inner lining. Giving shoes enough time to air out between uses can reduce accumulated moisture and help prevent strong odors.

Limited ventilation can cause moisture and heat to remain trapped inside footwear. Tight-fitting shoes and non-breathable materials may contribute to this problem. Choosing breathable footwear and keeping shoes in a dry, well-ventilated place after use can improve air circulation and reduce lingering smells.
Regularly cleaning removable insoles, allowing shoes to dry thoroughly, and keeping feet clean and dry can help control unpleasant odors. Shoes should not be stored while they are still damp. Rotating between pairs and allowing each pair to dry fully before wearing them again can also make a noticeable difference.
