OrthoLite uses aerogel for insulating insole
Insole provider OrthoLite has developed a thermal technology that traps aerogel in an open-cell PU foam.
The US company said O-Therm will keep feet warmer in cold conditions.
Rob Falken, vice-president of innovation at OrthoLite, said: "Our advanced aerogel traps micro-pockets of air without the need for loft, and it won't lose its effectiveness when compressed under foot. The nano-porous inside of a multi-porous structure creates a thermal barrier which blocks both cold and heat.
“O-Therm's advanced silica aerogel powder weighs in at only three times the weight of air.”
O-Therm is a 2mm base layer foam that can be combined with top-layer foams to create insoles for categories such as outdoor, casual, work, ski and snowboard.
