Fought off IT band issues a couple years ago, rebuilt slowly, focused on hip/glute strength and rolling.
Recently its been annoying me again and after watching myself in a mirror while on the treadmill to see if i could critique my own form, i noticed i was a bit “duck footed” when i ran. Not severe, but noticeable. Twisting my ankles out a bit created a more straight alignment and the IT band irritation went away in the past week.
Searching for this to see if anyone else had any experience, i came across this video that i thought i would share incase anyone else fights IT band issues.

The video pretty much perfectly shows exactly how my legs hang in a natural position like the athlete on table (along with similar flexibility issues).
Very interesting, I know that I have been duck footed for at least 5 years. I had always chalked it up to being my bodies natural body mechanics in order to create a more stable platform from side to side. Perhaps not though. Time to starts actually stretching every night!
You will have much better luck STRENGTHENING vs STRETCHING. Strengthen your internal and external rotation muscles and maybe some yoga. I dealt with bilateral ITBS for a full year. There is a bit more to it but that will get you started. I am writing a small/cheap e-book on it because there seems to be so much old and in my opinion mis-information on the web.
If the glute muscles (especially glute medius) have adhesions (knots) and are very tight they will externally rotate your legs causing the “duck foot” issue. Get rid of the adhesions on your own or go to a good ART provider. Stretching and strengthening will not be as effective until the adhesions and/or trigger points are dealt with.
thanks for posting the link. it is very interesting. seems to cut off in the middle of a sentence at 4:54. is there a continuation?
i have been running like a duck since i started running over 30 years ago. it is less pronounced at faster paces when i’m a little more forward on the midfoot, but pretty ugly on slower runs. got away with it for a while but have had knee and ITB issues off and on for 18 years. in fact, it was OK pre-triathlon while i was solely a runner, but the problems started about the time I started cycling more seriously. did some randonnee stuff for a couple of years, and then started triathlons. so i would like to blame the cycling, but that’s likely just my own prejudice in favour of running 
currently trying to fix a knee that is not happy at all.
ps, your link led me to http://www.mobilitywod.com/2012/01/episode-361-pathomechanics-and-it-band-hell.html
hey thanks for that followup link, never saw that.
Not sure if your ITB syndrome is bilateral. If one side is worse, check for a leg-length difference by measuring from hip (ASIS) to ankle. ITB pain is usually worse in the longer leg. In that case, you might try a heel lift (not more than 1/2") on the shorter side. Also, the more painful leg is often abducted (held out to the side).
