Is there an official: I seek only post?
It seems by the American boot size chart I viewed, that I am either a 10 1/2 EEE, or an 11 EE on the boot sizing chart. That's an East German Officer boot size 29 EE (German sizing.)
I've been looking til I am practically Chiss...well, blue in the face anyway.
Ebay and Amazon have a few choices, very few, and most are a size, or half-size too small.
