there's a huge new range of shock absorbers recently out! Sports Jock are good bras too but not as widely available. Shock absorber do different levels of impact for support, running needs 2+, I'm a C cup and use a level 2 crop top style bra, find them more than sufficient. I do a lot of weight lifting and plyometrics and find them a really good all round sports bra. I just buy the same size as my normal bras too, which is easy!
