I use D/DD regular bras and have looked for a sport bra with great support while running and soccer that you also don't feel like you are in a prison in. Yes it doesn't give as amazing support as those prison bras, but it's still great. I'm not a fan of bras that cut to close to neck, the weight that close on my shoulders give me a head ache. This bra sits nice wider on your shoulders giving you free mobility. I have never had a problem with the straps sliding off my shoulders.
This is my absolute favorit sports bra. It is perfect for high impact, but also for comfy everyday wear. The velcro straps makes it very easy to adjust the straps for any kind of wear!
