^Right. And as you point out, the sizing is affected by different factors. Style (tie vs. slip on, handsewn vs. Blake) and leather being the big ones. Maybe we aren't hearing from those who have been successful with the sizing chart, but it seems as if errs on the small side to the extreme. Not sure my Rancourt is so insistent that it's a good tool.
Wait...isn't the printable sizing chart on the Rancourt website just a paper version of a brannock? Sure looks like it to me and when I did it per instructions my size came out right at my brannock. BTW...just picked up these at the sale. Very nice in hand.
