Product Summary

The proprietary aerogel in OrthoLite® O-Therm™ traps micro-pockets of air without the need for loft and won’t lose its effectiveness when compressed under foot. Unlike other aerogel solutions, OrthoLite® O-Therm™ requires no special handling and or encapsulation—truly a world’s first!

Third party lab tests validate that OrthoLite® O-Therm™ is a breathable thermal barrier that is 54% more effective on average in comparative testing to other thermal insoles when tested at -78°C (-108°F), and only OrthoLite® O-Therm™ delivers all the benefits of OrthoLite® insoles—from maximum breathability, performance and unrivaled comfort. With the remarkable innovation of OrthoLite® O-Therm™, consumers can stay out longer, be more comfortable, perform better and go farther in cold weather conditions.


OrthoLite® O-Therm™ is the optimal underfoot thermal barrier, with a thickness range from 2mm-20mm, you can dial in the level of cold block performance based on the thickness of the foam you select. OrthoLite® O-Therm™ can also be combined with a wide range of OrthoLite® top-layer foams to create a custom insole solution tailored to a broad range of footwear categories.

Available in molded and die-cut applications, OrthoLite® O-Therm™ also makes it an ideal thermal barrier solution for footwear linings and Strobel layers—bringing unsurpassed cold block technology without adding bulk or weight.
