You are in the wrong boots. Blisters are a sure sign that the foot is moving in the boot.
This is so sad, but it happens. It shouldn't happen. You need a better bootfitter.
Where are you again?
I didn't start getting blisters until I put a shim in my boot to take up volume. I think that in combo with the high volume instaprint footbed raised me out of the heel pocket in the shell too much. At least, that is what it feels like. Without the shim, I am in the heel pocket of the shell, but I have forefoot slide (while sideslipping especially). This is even in zipfits. Can't seem to take up enough volume.
I'm in PA, but I've had boot fitters shrugging here, in Jackson Hole, and in Vermont. Maybe I just need to accept this?
