My guess would be that foot
My guess would be that foot changes in terms of length would all depend upon the amount of arch you started with.
If you had flat arches and the activity of BFR increased your arch then your feet would probably measure shorter.
On the other hand if you had overly high arches that became normalized while running in the bare your feet would probably measure longer.
My feet are noticeably wider and only fractionally shorter than before I started BFR. Thus far the change hasn't forced me out of my regular shoe size.... although I have a feeling new ski boots are in my future.
