Toasty Feet features breakthrough technology developed for NASA.
The advanced nonporous material in Toasty Feet has the highest thermal insulation value of any solid material available today, allowing it to block both heat and cold efficiently, while remaining light and thin enough to fit comfortably in almost any shoe or boot.
"Just before starting my Everest expedition, somebody told me about the Toasty Feet insoles. I checked it out and got a pair to test. It was only at the mountain that I unpacked them, cut them out to the right size with nail scissors, and replaced the original inner sole of my shoes with Toasty Feet. I’ve never walked on a different sole, but I started my way up. During the day my feet did not get any more sweaty than normal and even during our summit attempt, walking with temperatures as low as -25 degrees Celsius in the dark night, my feet did not get cold. Toasty Feet is a welcome supplement to my gear"
