Both rubber soles on my Clark leather sandals completely crumbled and fell apart leaving a very sharp metal support plate exposed. I am surprised that this hard rubber would disintegrate after very little wear making it impossible to walk in them. I was walking while attending an event and was suddenly unable to stand up when my shoes disintegrated while I was wearing them. This was a very dangerous situation. I want my shoes replaced or to be compensated to replace them. Clarks needs to correct their manufacturing error and avoid using this material.
