What is hydrolysis?

Sometimes the soles of shoes can start to crumble or even come off when walking, even if they have not been used a lot. This may appear to be a factory defect, but it is in reality a spontaneous chemical process called hydrolysis.

When boots are only used occasionally, the soles dry out and tend to harden, similar to what happens with car tyres, and a chemical reaction is triggered which causes the polyurethane molecules to split and the soles to degrade. This problem can affect both the outsole and the midsole.

It is therefore not a production defect, but a natural process of material deterioration, which manifests itself even more intensely if the footwear is not used often or has been stored for a long time.
