I also shoot hoops using my cheapo CX200 sennheisers or JVC FX40's with comply TS400 tips on them. And I only wear them during shooting drills which is non stop running and jumping. They don't even budge. I would think this is worse than running. Unfortunately there is no mic or remote but a similar model (CX275) is available with both features as well as the higher end CX980i which is going to sound better than those bose by far.
I quite using my Ipod however and use a zip clip with a 64gb card in it. It weighs so little that even if you drop it, your iem's still stay in your ears and it just dangles from the cable. Think early ipod shuffle in weight. It has actulal physical buttons on the front so it is easy to play, pause, rewind, volume, etc.
That is my best recommendation is to get comply foam tips. Just find the lightest IEMs that you can find with a mic/buttons and look them up on Complyfoam.com. There is a tip size finder there. The Sennheisers I have for example use the 400 size.
