If boxers and boxer briefs both ride up, then just...wear briefs. I do, since I've got the same problem. I mean, they still make them for a reason, presumably because not everyone likes boxers, despite the increased "cool factor". If you don't buy the white ones, then you're still ok if someone happens to see your laundry pile, or gets into your pants, they're still not *technically* "tighty-whities". And they do hold your packer better.
