Why are shoes so prone to breakage after not wearing them for a long time?

Why are shoes that have been worn for a long time less likely to have soles falling off or cracking, while shoes that have been idle become more prone to aging and brittleness?
Because shoes are affected by the weight of the human body and foot movements when worn, the air inside the rubber is forced out, which can to some extent slow down the aging of the rubber.
At the same time, the moisture released by the feet will also slow down the brittleness of the glue.
But idle shoes, with their rubber and glue exposed to air for a long time, are more prone to oxidation reactions, leading to problems such as shoe upper openings and sole cracking.
Moreover, if idle shoes are stored in damp or dark environments, they are more likely to breed bacteria and may also deform due to improper storage methods.
