I use smartwool when it gets cold. Some things to note, however:

If your boots are too tight, you will get colder feet. Ask any skier who has had frostbite because his boots were too small.

Consider wearing a warm hat. Keeping the head warm will help your hands and feet stay warm as well.

Walk more. Walking forces the body to run blood through your feet since you need it to have the muscles operate.

Stay energized. Eat properly, and if you are flagging, take in some sugar. After you eat, your body temp goes up.
