Me, too. I got some bad advice from Leffot that Grant sizes and Barrie sizes are the same. They aren't. That was an expensive lesson.
Other than some who wear the same size in both, what you guys are saying makes sense and could reinforce what Robert at Alden-SF told me (that Grant is basically a Barrie with a sleeker toe). I.e., the sleeker toe of the Grant necessitates going up a half size from the Barrie. My question to you guys is do you feel the lasts are the same from about the ball of your foot to the heel?
