SAEDNEWS: Regular drying, cleaning, and proper storage can help reduce unpleasant odors in sports shoes by limiting moisture and the buildup of odor-causing microbes.
According to SAEDNEWS, sports shoes can develop an unpleasant smell when sweat and moisture remain inside them for long periods. The warm, damp environment can encourage the growth of microorganisms that contribute to odor. Keeping shoes dry and cleaning them appropriately can make a noticeable difference.
After exercise, remove the shoes and let them air out instead of leaving them in a closed sports bag. Take out the insoles if possible and place the shoes in a well-ventilated area away from direct heat. Strong heat from radiators or other sources can damage some shoe materials, so gentle air-drying is preferable.
The insoles often absorb sweat and can contribute significantly to unpleasant odors. Check the care instructions before washing them. If they are washable, clean and dry them completely before putting them back into the shoes.
For washable sports shoes, follow the manufacturer's cleaning instructions. Avoid putting shoes in water or a washing machine unless their care label allows it, as excessive moisture or agitation can damage their shape, adhesives, or materials.

A few everyday habits can reduce odor buildup:
Let shoes dry completely between uses.
Remove the insoles when appropriate to improve ventilation.
Keep sports shoes in a dry, ventilated place rather than a closed bag.
Wear clean, breathable socks and change them after exercise.
Avoid wearing the same pair continuously when another suitable pair is available.
Clean shoes according to their material and care instructions.
Persistent odor may mean that moisture is repeatedly accumulating inside the shoes or that the insoles need more frequent cleaning or replacement. If the shoes remain damp or develop a strong smell despite regular care, replacing worn-out insoles or, when necessary, the shoes themselves may be more practical than repeatedly masking the odor.
The key is not simply to cover the smell but to reduce the moisture and residue that allow it to return. Consistent drying, appropriate cleaning, and good ventilation can help sports shoes stay fresher for longer.
