When you have a fungal infection on your toenails, walking around in shoes can be uncomfortable, and it is essential to disinfect them to prevent re-infection. The most effective way to disinfect shoes from fungus is to use a UV sanitizer, which is available in models specifically designed for shoes. Alternatively, you can use a mixture of hydrogen peroxide and baking soda or vinegar to eliminate fungus from your shoes. It is also helpful to let your shoes soak in the sun for a while to enhance the disinfecting process.
