I just bought two of these. (I need to get rid of all my old athletic brassiers, so I am stocking up.) I have worn them each once to the gym, once on the elliptical and once to my step aerobic class. I think it does a good job of shock absorbing. I am not thrilled about the front seams showing through my gym shirt, though. Also, I am not sure if it does a great job of wicking and drying. Since I think shock absorbing is the most important role of a sports brassier, I gave it a high rating. After a few more test runs, I think I will be buying more.
