You don't want a shoe that rubs your feet raw when you run, but you do need enough padding to keep your feet comfortable for your 4 plus hour run. You also want enough cushioning to reduce the impact on your joints. Dance/Cardio/Plyo/Martial Arts/Aerobic Workouts For these workouts, you need something that is both flexible and supportive.
