Colour Transfer from PU Shoe Linings: What to Check Before Changing the Material
A stain on a sock or a light-coloured shoe component is a reason to investigate the contact between materials before replacing the lining.

Then choose a test that addresses the suspected route: rubbing, moisture exposure or prolonged contact. A photograph can document the symptom, but it cannot establish the cause or prove which material supplied the colour.
