I tried this on at the same place I tried the Juno bra (a local running store). After seeing the rave reviews here, I had high expectations for this bra. Just looking at the difference between this and the Juno bra, I realized this one probably wouldn't have quite as much support (since it doesn't have moulded cups), BUT as a runner, I like my breasts being able to breathe a bit. I also thought the underwire would give a good bit of support too. I thought that overall, it would be a decent bra.

Well, I was wrong. Unlike some of you, I had the luxury of trying on a variety of sizes (34D to 32C) even though I'm sized at 34D. Nothing fit quite right though. The material just seemed too stretchy or something (I can't think of the right word). It was just too lose, no matter how tight you pulled it. I'd say the cups were too big, but I even went down a cup size. Perhaps the problem lies in the straps. Overall, the bra looks a lot more stable than it actually is. Granted, I'm a runner; I need my breasts to be held in place. Those of you who spin or do pilates will probably find this bra fine (although, be wary of the sizing: I'm a 34D and a 32C fit the best). Also, the underwire was comfortable and did give a good amount of support; the rest of the bra just didn't help the underwire at all.

Overall: I would go with the Juno bra over this for most things, and for purely running (i.e for those who want a thinner, less bulky bra), I'd go with the Shock Absorber Run bra.
