Most sports bras in this price range do nothing to make running acceptable without at least 2 bras. I can do jumping jacks and jog without wanting to scream. I thought it was odd to have velcro holding the straps, but it seems to be doing just fine. The bra was a little stiff and uncomfortable when I first tried it on, but now that I've washed and worn it it's very comfortable. Buying a second one now!
