From my Samples, Singulars, and Somethings Completely Different collection -
Brand-new production discontinued boots by GDFB (Get Dressed For Battle). I picked these up for myself knowing that they may be just a bit too tight for me to wear with arch support insoles, and indeed they were - they are listed as 12 1/2, but to be sure they're going to fit you I'm going to recommend these for size 12 feet. Brand new and unused, tried on once. Original MSRP was $182.
