@Ryan Dietrich as
@Jilly just said, enough has been said already. You have the information you need. Spend the money for the best boot fitter you can find.
The following is my experience as someone who went from a "comfort" fit to spending 8 hours a day in boots and being on the hill 70 days a year.
For your own information measure your foot. This will give you a rough starting point for what size boot you may need. Stand on a piece of paper and draw an outline of you foot. Measure the length, toe to heel and measure the width across the ball of the foot; do this in centimeters. For me those measurements are 27.5 cm long by 92 mm wide; I wear a size 11A men's street shoe. From this you may think my boot size is a 27.5, wrong, I'm in a 26.5 Head 120 RS. Doing a shell fit with the 26.5 showed over 10 mm space in the shell length. The 120 RS is built on a 92 mm last so the width is close. I have one small punch in each boot for the "sixth toe". I have custom foot beds because I have flat feet. The boot soles are canted because I stand bow legged but I ski knock kneed; this means the cant is opposite of bow legged. I have a 1 mm shim under the left liner, on top of the boot board, because of a leg length issue. I'm not that good of a skier but yes I can feel the difference with the 1 mm ship. That's what it took to get the skis to glide flat. All of the above took several trips to the boot fitter. But, the result is I can spend 8 hours in boots and my feet don't hurt and their not cold, except when it get's below zero, then I wear a Boot Glove.
As a side note, my wife who wears a size 8 street shoe is in the same size boot. Her reason is she has a very high instep and it took that size to the the volume she needed.
Do a shell fit with your Superchargers. If you have over 15 mm space behind the heel, with the big toe just touching the shell, your boots are too big. Regardless of the liner packing out.
So, I really haven't added anything to the conversation. Just get thee to the best foot fitter you can find.
