OrthoLite, the American insole specialist, has launched O-Term, a new thermal insole technology using a proprietary aerogel providing high performances in extremely cold weather.

Rob Falken, vice president of innovation at the company, explained that the “advanced aerogel traps micro-pockets of air without the need for loft, and it won’t lose its effectiveness when compressed under foot. OrthoLite’s aerogel is unlike any other aerogel solution in that it is nano-porous inside of a multi-porous structure, and that creates a supreme thermal barrier which blocks both cold and heat. In addition, O-Therm’s advanced silica aerogel powder is the lightest man-made material, weighing in at only three times the weight of air.”

OrthoLite said it has worked with a third-party thermal test laboratory, Vartest Laboratories, to quantify the thermal performance of O-Therm aerogel insoles at minus 78°C. The test results showed that it is 54 percent more effective on average in comparative testing to other thermal insoles at that temperature, it noted.

“We see tremendous potential in the (footwear) market - in cold weather footwear applications and beyond,” commented John Barrett, the president of OrthoLite.

OrthoLite is headquartered in Amherst, Massachusetts. It claims that its open cell foam technology can be found in more than 500 million shoes across all categories each year from brands such as Adidas, Asics, Bata, Clarks, Cole Haan, Converse, Danner, Ecco, Everlane Jordan, Kenneth Cole, Lacoste, New Balance, Nike, Reebok, Rothy’s, Sanuk, Timberland, Toms, Wolverine and Vans.
