I had two pairs of Iron Heart x Viberg engineers - 8.5D and 8.5EE. On the brannock, I measure 9.5D (L) and 9E (R). The 8.5D's were incredibly small - much shorter and narrower than my 8.5 2030 service boots. I sold those immediately. My 8.5EE pair was wearable, only because of the width and volume. They were too short for my left foot, though - the footbed measured 10.5", and my left foot with a sock measures 10.4".
