You have a great point, at this moment in time I'm just starting to suffer paralysis by analysis. I did pull out the footbeds and you suggested, and they do line up almost perfectly (I'm talking within' 1mm of each other). The Vapor feels better all around, heel sits deeper, toes don't brush the caps, they are the winner for me, I'm done. SuperTacks go back this weekend. Thank you all for your input over the past few weeks!
