Earl are you a doctor or something?
Anyways most people with Raynauds syndrome go undiagnosed and it's something I picked up on about 5 years ago after doing some serious custom work for a client of mine that had it on his ski boots. If all else fails there's 3 things I recommend. 1. Hot Tronic or Thermic boot heaters for your boots (burton does make a boot with them but it's fucking pricey), intuition liners, and those super feet with the metal flashing underneath to help insulate and send heat back towards the foot.
