O-Therm Thermal Insoles

The OrthoLite O-Therm™ is an innovative thermal insole technology for cold-weather footwear protection. This insole offers all of the known benefits of open-cell PU-foam, while combining a very light weight and insulative cold barrier protection using a proprietary aerogel. OrthoLite’s aerogel is said to be unlike any other aerogel solution in that it is nano-porous inside of a multi-porous structure. This new technology creates a thermal barrier that blocks the cold and maintains footwear temperature regulation. Additionally, this advanced aerogel traps micro-pockets of air without the need for loft, and it won’t lose its effectiveness when compressed under the foot. It repels water and moves moisture away from the foot to provide a drier, more comfortable shoe environment.
