Rob moisture in the air could lead to dampness and mold on your shoes if they are left for a while. I had the same problem in my room, like benji said silica gel should sort it out a pack in the box should be fine but you need to dry the gel out in the oven every few months as it only holds so much moisture. Im not sure if you can by it commercially but i got 1kg of it from work impregnated with an indicator which lets you know when it needs dried. Hope this helps.
