I saw this thread in boxingscene and thought it'd make interesting discussion. Here are some pics of standing beside 6"2/3 Larry Holmes and there doesn't seem to be much of a height difference between them. Wlad is listed as 6"6 yet it looks like about an inch difference between them. Larry is standing slightly in front in some but that's not enough to skew appearances. Doesn't look like he's wearing thick shoes either.
i think photographer angles and distance really make it appear like this in a shot. kinda looks like hes hunching over a bit too
