Hi Elanelaine,
I think they tell you by the notation MCR, which stands for motion control something. Some are Med MCR, some are High MCR and some are Max MCR. I think with running you would want to go with the Max MCR. I just ordered two of the powerback underwire sports bras with High MCR. If you are a c cup for less they are Max. I hope I like them! If not, I'll just send them back. It will cost a few bucks but who cares because they are such a great deal plus free shipping. I ordered a few tops too.
