Shoes are indispensable items but easily retain unpleasant odors due to sweat and bacteria accumulation. Shoe odor not only causes loss of confidence but also affects health. So how to quickly and effectively remove shoe odor. Don't worry, the article below Shondo Blog will introduce you to extremely easy ways to remove shoe odor , eliminating odors in just 30 seconds!
1. Causes of shoe odor
- Foot sweat: Sweat is an ideal environment for bacteria to grow. When wearing shoes, especially sports shoes, and exercising a lot, the feet sweat more, creating moisture inside the shoes, creating conditions for bacteria to grow strongly and cause odor.
- Bacteria, mold: The damp, dark environment inside shoes is a favorite "home" for bacteria and mold. They decompose sweat and dead skin cells, creating compounds with unpleasant odors.
- Improper shoe cleaning: Not cleaning shoes regularly or drying shoes improperly causes sweat and dirt to accumulate, creating conditions for bacteria and mold to grow, causing bad odors.
- Shoe material: Each type of shoe material has a different ability to absorb sweat. Leather and fabric shoes usually absorb sweat better than plastic shoes, so they are more susceptible to getting wet and smelly if not cleaned regularly.
