Toasty Feet are insulated with Aerogel, which was developed by Aspen Aerogels for NASA, and is claimed to have the highest thermal insulation value of any solid material available. Their website claims an R-Value per inch for Aerogel of about 12, compared to about 4 for Thinsulate and 2.5 for fiberglass. The Toasty Feet Insole reduces conductive heat loss from the bottom of the foot. So, how do these insoles insulate when you are standing on them?
