OK so assuming my coveralls from herotekX fit, the only thing I'm missing at this point for approval is boots!
However every link/thread on here talking about them is YEARS out of date, so practically any boots they list are either out of production or at best around in limited quantity/sizes and because of that I was having a REALLY hard time finding any boots that fit the criteria AND ME!
But after some searching and a bit of back and forth running a couple different boots past my garrison GML, he did find one pair online from JCPenny that he said would work WITH A LITTLE MODIFICATION!
The Frye and Co. Mens Orson Flat Heel Motorcycle Boots
My GML recommended that these would work provided the ridiculous buckle/strapping AND the top loop was cut away as cleanly as possible.
He even marked out where/what to cut for me, so I'm gonna pass those images along on here so hopefully this will help anyone else like me who is trying to put an IAT together at present.
