I read somewhere that athletic shoes don't last. 20-30 years, and they crumble away, even if left untouched in the box.
I suppose it's like the foam insulation on my '72 Dodge - touch it and it turns to dust. Some of the plastic parts crack and disintegrate. Rubber falls apart. It was never designed to last this long.
