[Squeaky]

I always read that sneakers should be stored in dry and dark places. In my new supe room the window is open during the night, almost every day. Even in the winter. Is that a problem for my supes that are stored on my shelves? During the day, the window is closed. The curtain is always closed so no light problem.

What is the damage moist in the air can do? I know that sunlight can discolor shoes.
