I see no correlation, or any benefits between barefoot running and yoga. In yoga you are stagnant and bored, running barefoot you are moving and having fun. I suffered a fierce IT issues years ago, I looked into the whole yoga thing, PT, and stretching. All three were unsuccessful in curing my ITBS. First thing first, never stretch for IT issues. Yoga is the worse thing you can do if you suffer from ITBS.
The IT band is not meant to be lengthened or stretched. The common problem that causes IT issues is weak out leg muscles that lie underneath the IT band. You need to do air squats, lunges, various leg exercises, and in my opinion, the best workout to cure ITBS is kettlebell swings.
