If composition soles are stored for any length of time they will disintegrate---not only hotter as I had a comfy pair of K shoes which I'd worn alternately to others and they too showed signs of " perishing " even though on the face of it were fine visually.
This is true, it’s the material ( non leather soles) is it polyurethane? Anyway, a black rubbery sole.We had a thread on this a few years ago, with lots of examples if you can find it.
The prevailing thought seemed to be age of shoes and storing them in cramped airless conditions.
Anyway, it was Hotter, Clarks and several other makes.
