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.
The chemical reaction needs air which it was not getting in your boots. That is the major problem with chemical warmers. Take them out of the package in advance so they can reach maximum temperature before you put them in your boots. Better yet, put them on top of your boots over the toes so they get air and produce maximum heat. You can hold them in place with a velcro strap or oversock or shoe cover. Heatmax makes good warmers so you don't need a different brand.
