Replying to Boot help

I have always struggled with finding a boot I like and that fits me well I purchased the k2 method flex this year hoping they would fit me well. They didn’t I don’t understand am I buying the wrong boots I ski a 27.5 and have yet to find a boot that holds my foot down and makes me feel connected to the ski. I got sick of that shit and went out and bought a thick piece of foam and cut it into the shape of my foot bed now I love my boots and feel like I can ski better than ever it had helped me spin and has improved my rail skills greatly. The difference was night and day I need some boot recommendations i feel like I shouldn’t have to diy my new boots to fit my foot plz help why do boots not fit me?
