Just tried this bra out on a 3 mile run.  I am a 36DD and I really felt good in this. I have spent a large amount of money on other sport bras, but this bra really lived up to its hype.  I am so happy the under wires that were in my old bras have disappeared, no more blisters and bleeding from those nasty wires. Yet, I still feel like I have full support, even when I am in a full sprint.  Also, my old bras that I paid the same amount for showed unsightly seems underneath my shirt and I was embarrassed to wear these bras while around other people.  This bra is so silky smooth and no seems appear.  It magically lifts my breasts and makes me feel years younger.  Even my six year old daughter innocently exclaimed "Mommy, you look young again!"  I just love the feel of the fabric in this bra,it is so silky, and it seemed to wick away my moisture effectively during my run. My only complaint would be that it is difficult to fasten the back top of the bra without help.  My husband helped me the first day I wore it, but on my second try I was successful without his assistance.  Also, the top closure felt a little awkward at first, but I got used to the feeling as I ran and experienced no chafing at that point of contact.  So overall, yes the bra is expensive, but I would never hesitate to purchase running gear that I find has a great fit. Especially where my breasts are involved. I have loved running ever since I could remember.  Running helps me stay a positive person, even when life sends me some real challenges.  When I was younger and began to develop larger breasts, I felt sad that I couldn't find a product that would let me enjoy one of the true loves of my life.  But this bra helped me to feel rejuvenated and young again.  I am sure all of us who fit into the category of needing supportive sports bras know how it feels when the merchandise we are wearing up there doesn't live up to its reputation.  I am happy to say in this case, the product did and I am not embarrassed to step out the door anymore and do one of activities I love most in life  - run.
