Does anyone run with no shoes on? I heard or read somewhere years ago that it was better for you. Since I'm stuck at home now and not going to the gym I decided I would run on the treadmill with no shoes today. I have a feeling the soles of my shoes absorb the shock and I will probably have sore knees, hips, etc tomorrow. If that's the case, should I push through and keep doing it? Is is worth it?
