In general, IT band sysndrome is one of those conditions that tells you pretty quickly when you've done something to irritate it. If you're noticing IT band pain after running, your energy would be best spent trying to figure out what it is you are doing while you are running that is making it worse. If you're not having pain riding, I doubt that changing your float will change your symptoms much. But I do agree with what others have said here about checking that you are in the center of the float and also that you are not collapsing inward through the forefoot.
Stretching the muslces that attach to the IT band and using a foam roller are the best ways to address tightness issues related to this problem.
The most common form related problems that irritate the IT band a lot are:
1) over striding out in front which usually comes with heel striking.
2) crossing over in front at initial contact with the ground (this is really bad if you are also doing #1)
3) collapsing inward through the hip/knee/foot when you are fully weight bearing on the leg (can also occur in combination with 1 and 2)
I'm going to head over to the running forum and start a new thread with some information about running form and the drills to correct them.
Living life like there's no tomorrow.
