A couple of months ago I was invited to go hiking with some friends. When preparing, since I didn’t have some hiking boots, I saw my boots that I got in my military service. That was a great idea because they were already broken in and all of that stuff.
After around 3/4 of the almost 15km hike, I lost the sole on the first boot and a km after that the other side. Had to finish the hike on both without a sole.
Well, they were standing around for like 10 years so I am not surprised that they failed and that the whole stuff between sole and shoe Desintegrated but still.
Most likely they were stored in a warm and humid place. Polyurethane foam can get something called hydrolysis, where moisture breaks down the polymers in the foam.

10 years without being oiled, i guess. The leather would dessicate, maybe?
My soles have a cork layer that seems like it would crumble even if well treated.
