Replying to Cold toes, new boots, and frostbite

So I have bad circulation, and I have since I can remember. Ive always had colder feet, but This season, its gotten to the point of my feet getting so cold at about the 2.5 hour mark that they go numb, and Ive gotten minor frostbite 3 times this season on my big toes.

I had Nordica Ace 3 star boots for 3 seasons and while my feet got cold, It was never bad enough that I would have to stop skiing.

I Just bought new boots (Hawx ultra 120s), and my feet have never been colder in my life. after 3 runs they are freezing and cold as fuck. I have to unbuckle everything after every run and it still doesnt help much.

These boots were fitted by a professional, and there are no pressure points. I like a tight ass fit in my boots, but I dont buckle them so tight that my circulation gets cut off.

There is zero chance that buying a boot heater will work because I will just break it. Im going to start investing in boot warmers, but thats a short term solution. The most noticeable change thats happened this season is that I put my booster strap under the shells, so its only tightening the liner to my leg. I was told to do this by a bootfitter and I love how it feels. Ive never heard of a booster strap cutting off circulation though, and I dont tighten them too much.

I need advice.
