Disclaimer: I got weird feet. high arch, different lengths/width, pronation, and stupid wide last. Not everyone will have the same issues I had.
That being said, I would heavily advise against level 9. They did a one size fits all type fitting, (worked for my girlfriend who has more normal feet) while happily running up my tab making adjustments but not doing any measurements; except for when I asked her to she pulled out a tape measure and measured my last. Turns out she was about 6mm too narrow and fucked my feet for half a season.
Next I went to Sports Den, the old dog I worked with initially seemed very knowledgeable, and helped fix the pisspoor footbed level 9 had done. They did a digital scan which was far more detailed than anything level 9 did, but still felt inconsistent bc I had different measurements each time I did the scan. When I went in for new boots, they had a fleet of high schoolers doing fittings and modifications and it definitely felt far less knowledgeable, so if you go to Sports Den, only work with the old dogs as they actually have experience and know whats up.
Due to the poor experience with the 16 year old when I went to sports den, boots still hurt like a bitch when I skied so I said fuck it and spent the extra cash (that I should have spent initially) and went to Gorsuch in Park City. The guy there has been fitting ski boots for 35 years, so he explained in immense detail what he was changing and why. Not only was he knowledgeable, but he 3D scanned my feet and digitally put them in to 3D models of the boots he wanted to try. Their software highlights the areas where it would need stretched and told him how far to mold the shell, resulting in a way more precise fitment than "where do you feel pressure? okay ill stretch around that area and we will keep trying"
Again, maybe I had a unique shitshow of an experience, but after dropping $1500+ on 2 pairs of boots and many fitting sessions, I wish I went to Gorsuch and did the expensive fitting the first time. Mine came out to about $1150 for the 2023 boots and fitting
