I'm sure others will be along to answer too. My feet get very cold, yet I can't say freezing. Three years ago when I was working at a convience/gas station and on my feet for my entire shift, my feet burned. In the last 2 years, they rarely burn, they ache, sometimes are numb, and they both have a certain area that swells.

Now Kev has diabetic neuropathy and his feet are always cold, ice cold to the touch. He always says he thinks it is caused by poor circulation. So, I would imagine, you will get many answers.
