TL;DR - if you get cold hands/feet at night when it's cold outside, and would like to be warm and toasty in bed, these work great as long as they are exposed to air/moisture.
Perhaps even a year ago now, I purchased a box of Little Hotties Hand Warmers in the hopes that they would keep me warmer on really cold nights when we stayed up around the camp fire until way past my bedtime (midnight or so). I've used them a couple times since then, but I always tried putting them in my shoes as we were around the fire, and that never seemed to work - I think because they didn't have the necessary air flow to trigger the chemical reaction that gives off heat.
On the Colorado trip, I took a different approach. Instead of using them around the fire, I placed them in my socks when I got into bed. This way, they had more exposure to air. It worked great. They warmed right up and kept my feet warm for 8+ hours. That in turn kept me much more comfortable in bed. Will do again.
