Odor in shoes is often caused by the growth of bacteria on the feet or inside the shoe. Bacteria thrive in warm, moist environments, and the inside of a shoe can provide the perfect conditions for this growth. Additionally, the bacteria themselves can produce unpleasant odors.
PU insoles can help to prevent odor in a few ways. First, they absorb moisture, which can help to keep the feet dry and reduce the amount of moisture available for bacteria to grow. Second, PU insoles can provide cushioning that helps to reduce friction between the feet and the inside of the shoe, which can also help to reduce the amount of moisture produced. Finally, many PU insoles are treated with antimicrobial agents that help to inhibit the growth of odor-causing bacteria.
It’s important to note that while PU insoles can be helpful in preventing odor, they are not a guaranteed solution. Regular cleaning and airing out of your shoes is still important to prevent the buildup of bacteria and odor over time. Additionally, if you have a persistent problem with foot odor, it may be worth talking to a healthcare professional to rule out any underlying medical conditions.
