I recently bought a pair of used CL on ebay. I love them but the soles of the shoes are worn, or so I thought. I took them to a cobbler and she said it was just the red paint that’s worn off and not the actual sole, so I was wondering if there was any way to get the red back? It’s only on the part that is walked on that is worn obviously. Does anyone know how to refurbish it? I know the chances are unlikely, after all what would stop most people from painting their soles red to get that look? Would CL fix them? Would it be better to just get that part covered with a patch of nonslip rubber?
