I have never noticed the heat you speak of at my right boot area, of course riding and owning it for 4 years tends to get you used to things. I can tell you without a doubt that less heat is noticeable with the Area P can and midpipe than the bazooka OEM system. The foam inserts really do help from what I hear concerning overall heat, but can't say much about the foot heat you felt. I can tell ya that the heat sure feels good at certain times of the year though.
