Title: THE BEST -- MY FEET ARE FINALLY WARM
Review: I loved my battery operated warmers but they were costly, broke at least once a season, had to be replaced and cumbersome. Finally, an easy to use, inexpensive way to keep my feet from getting cold. I have poor circulation in my feet and have tried everythng from the battery insoles to taping hand warmers to my socks and using pepper rubs in plastic bags. As a scuba diver, I thought this just might work. And it did. My feet aren't what I would call toasty but they certainly are "warm" enough, they have feeling in them and I am comfortable all day which is what matters. And that is with one pair of medium ski socks. I am thrilled to have found these and even more so by the price and ease of use. I haven't tried them in below zero (F) but they did well in single digit temps that warmed to the teens.
