Planemad2. You don't have to take off your shoes in an emergency evacuation - in fact you would be crazy to do so due the possibility of trying to escape over jagged metal and maybe even burning debris. In one accident in Spain where people were told to discard shoes, several passengers were so seriously disabled by traumatic foot injuries caused by ripped metal on the ground that they were caught in the fire. Maybe a different story if you are wearing stilleto shoes which might puncture the slides (or dinghy) - but that becomes your problem.
