With the approach of colder weather, keeping your feet warm starts to come to mind. I am usually cold by nature, so when the temperature starts to drop, I start to look for solutions to keep my feet warm. It seems that if my feet are warm, it helps to keep my whole body warm. Lately, I have started to use the kind of foot warmer insoles that start to heat up when you open the package. These things keep my feet warm for hours, whether I am outside in the cold or sleeping with them on my feet.
You can buy several different kinds of foot warmer insoles, and I suggest keeping a supply of them on hand, particularly if you are outdoors much in colder weather.
