light weight, comfy, and not terribly expensive. A little thin in the sole, and shell, but that is what makes it light. I will buy another pair. also, they come in size 13!
These things work as expected. The intent is to keep your feet at body temperature. I just used these over the weekend on days where the temperature was ZERO... they worked. I like the fact there are no wires (I have ski boot heaters with wires and BIG batteries). The smartest way to use these insoles is to put them on medium to get the maximum time.
I purchased these for my husband to replace some worn out boots. He wears them on a motorcycle and says the soles are very grippy and comfortable to ride in. He's worn them riding in the cold down to the 30s and has said his feet were warm the whole time. I bought them because they are waterproof and they come in wide sizes. So far they hold up great in harsh weather. and I hear nothing but raves. I'd definitely recommend them.
