Storing the shoes for a long period of time can be challenging, especially if you have been wearing them. The inside of the shoes would contain a lot of bacteria from your feet. If left undisturbed, these bacteria can multiply and produce a foul smell or, in the worst case, destroy your shoes. However, there is an inexpensive solution to prevent this from happening. You can spray both the inside and outside of the shoes with shoe disinfectant spray. A method that is even cheaper than that is to clean your shoes thoroughly before storing them for the long term.
