Normally I avoid going outside on the bicycle if the temperatures are lower than the twenties. Today I needed to get a prescription for my dog. While out I went to three other stores to buy food. The high temperature was about nine degrees when I left home. When I arrived home the temperature was about seven degrees. At the last store I bought some chemical heaters for my boots because I wouldn't have enjoyed riding the last four miles.

I bought an extra set to keep in my tool kit just in case I need them. They worked OK. The two sock layer needed some help. When I removed my boots about an hour after getting home the warmers didn't seem to be putting out much heat. The label says they can last up to six hours. They had only been in my boots for an hour and a half. These were my first ever chemical heaters. I'll try a different brand if I ever buy more of them. These were called Toasti-Toes by Heatmax.
