What causes shoes to crumble?

Hydrolysis is the chemical breakdown of the PU polymer and the resulting physical breakdown or crumbling of the PU sole by the attack of water (usually in vapour form), occurring over a period of several years (even when the shoes are in store!). This process is accelerated by warmth and high humidity.

Will shoes crumble over time?

Their role in degrading polyurethane can be attributed to the chemical processes of hydrolysis (in the presence of moisture) and oxidation (in the presence of oxygen).

Do leather shoes degrade?

Dry rot is the process in which leather degrades due to the lack of moisture in the material. When all the oil from the leather evaporates, the fibers in the material become brittle and crack, which leads to permanent damage. This process usually occurs if your leather footwear is kept in warm, dry conditions.
