Replying to Marker squire mounting help

So I'm putting a pair of squires on an old pair of skis I have laying around to use to beat up either in my backyard or while hitting urban. I did some research and the mounting template is the same as the griffons and jesters. So I printed it out, found the center point lined up the toe template which is all good, but I don't understand how you use the heel template (there are two pieces of paper to the template heel and toe) there are boot sizes with tick marks but i dont know how to match them up. If someone knows how to line it up that'd be great!!! I'll put some pictures in but I'm on moble right now. It's hard because there are no directions with the template when you print them out.
