Hummm don't know, I have neuropathy in my feet but mine are always hot even in the winter. I know many folks that have cold feet and hot feet that don't have diabetes so I am thinking is has nothing to do with the disease.

Did you get your feet really cold years ago, sometimes the nerves can be damaged. I have diabetes and they used to get hot but it was some rubber flip flops doing it when I wore them in the house all the time. Since I have been doing alot of water exercising my numbers have dropped ALOT and feet are fine.

?Diabetes can certainly affect circulation, esp in the hands and the feet, which can make them cold

There are 2 things you could do. Pick one.

Drink Beer
Take a 500mg capsul of L-Arginine

The alcohol pushes your blood away from your body and it eventually gets to your feet. It's nice and safe because everybody drinks beer anyway.

The arginine, well...
Arginine - The Source of Nitric Oxide

Another natural way to help improve blood pressure is with nutritional supplements. Arginine, an amino acid that is vitally important for overall good health, may be a potent weapon in the fight against hypertension. Besides playing a positive role in blood pressure control, arginine (technically, L-arginine, but the L can be taken for granted) can also be helpful in a variety of other conditions, including type 2 diabetes and sexual dysfunction in both women and men.

So how does arginine work its wonders? The answer lies in its ability to produce nitric oxide (NO), a simple gas made up of nitrogen and oxygen that performs some amazing feats in the human body. In fact, NO is such an important molecule that the 1998 Nobel Prize in Medicine was given to three scientists for their pioneering research on its role in human physiology.*

have your doctor check for nerve damage or even a blockage in the arteries in the legs could do this
