How do Toasty Feet Insoles Work?
The thermal barrier is nanotechnology aerogel. This technology, developed for use in outer space by NASA, provides the most effective barrier to heat loss and gain through the sole of your shoes. Without the protection, your feet will become the temperature of the ground or surface on which you are standing. With the patented aerogel insulation, your foot temperature will remain constantly comfortable, avoiding the heat loss and gain you would otherwise experience. Unlike traditional insulators, aerogel does not lose its effectiveness when compressed – so Toasty Feet can withstand pressure underfoot without losing insulating performance. Nanotechnology in footwear keeps your feet comfortable!
What’s Behind the Performance of Toasty Feet?
Provides 39 times more insulating capacity than the best fiberglass insulation. It is 1,000 times less dense than glass.
What is Aerogel?
Aerogel is the lightest and lowest density solid known to exist. It is typically 50-99.5% air, yet can hold (theoretically) 500 to 4,000 times its weight in applied force. Aerogel can have surface areas ranging from 250 to 3,000 square meters per gram, meaning that a cubic inch (2.5 cm x 2.5 cm x 2.5 cm) of aerogel flattened- out (again theoretically) would have more surface area than an entire football field! Aerogel’s super low density makes it useful as a lightweight structural material, and its super high internal surface area makes it a super insulating solid material. Aerogel is not like conventional foams, but is a special porous material with extreme microporosity on a micron scale. For those of you who have always wanted to touch an aerogel, it feels like styrofoam. Silica aerogel is transparent with a blue color.
