What is the best way to keep and store tennis shoes? Recently, I bought 4 pairs of Barricade III at a good price (simply love the shoes!), and am worried about them disintegrating if they are kept for too long. I forsee that I may have to keep for at least a year before I use the last pair. Anyone has any advice on what is the best way to keep them, and would I have problem with the shoes if they are kept for too long? Thanks in advance.
