How does the insulating material, aerogel, work?
The thermal barrier is nanotechnology aerogel that was developed for and used by NASA in space suits and spacecraft. This technology provides the most effective barrier to heat loss and gain through your shoes or boots. Without this protection, your feet will become the temperature of the ground on which you stand. With aerogel-infused insoles, your foot temperature will remain constantly comfortable, avoiding the heat loss and gain you would otherwise experience. 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
