Query: Horrible for Running

I wore these for a run and couldn't even believe how bad these wore. I ran 3 miles and by the first half mile i had to take them off because they kept bouncing out of my ears. If you sit still these are decent headphones but even walking makes these bounce out. I have normal shaped/sized ears and was greatly dissatisfied with this product.
