I was in Korea Aug 50 - July 51. My combat boots provided little protection from the cold, but I never went as far as frostbite, as far as I know. I have now, for two or three years been suffering from foot neuropathy that, without medication and sometimes with medication hurts like hell. I came away with malaria, and my wild life style brought me down about 10 years ago with diabetes and high BP. If I can be more helpful, let me know.
