Best high impact sports bra for small boobs?

[littlepieces]

Any recommendations? I'm 32B and do a lot of running. I struggle to find a supportive sports bras that aren't designed for big boobs. Really thick straps and bands feel quite restrictive/cumbersome, and unnecessary on me. I got a Lululemon Energy bra a few years ago in a sale that's quite good, but is more compression than support. My budget is £40 max.

I tend to get Decathlon.

Small sports bras often suffer from the old style bra sizing issues of smaller cups/ bigger backs. I do wear 32B often because the better cut 30C is too rare. 32B is wearable as a sister size but a bigger cup does fit around the sides better. It might be worth looking into whether you actually are a 32B or are wearing it because it's the more common small size avaliable.

Shockabsorber , not cheap but can usually get them cheaper on Amazon in the not so popular colours , I wouldn’t wear anything else for running
