For me the most recent issue with my IT was directly related to new shoes/cleats. Following an adjustment of the cleat position and a rest to let the IT band 'heal' I was good to go. Changing out cleats on the same shoe is relatively easy, just mark the location on the shoe before swapping, but getting it right on a new shoe/cleat setup can be a bit more difficult.

Good luck, I know it sucks not being able to ride when you want to but rest is required.
