Now you can add a layer of insulation and comfort to your boots with the OrthoLite® O-Therm™ insole technology – 54% more effective on average in comparative testing to other thermal insoles. OrthoLite O-Therm insoles can be combined with a wide range of KLIM footwear.

• Eco Friendly: All OrthoLite® foams contain 5% recycled rubber, helping keep hundreds of tons of waste out of landfills each year.
• Long-Term Cushioning: Unlike traditional insoles, the compression set of OrthoLite insoles is less than 5% over time so the cushioning and fit never change inside the shoe, providing maximum comfort every time you put your shoes on.
• High-Level Breathability: OrthoLite’s open-cell PU foam is 95% to 100% breathable, allowing air to circulate in and around the insole, keeping the foot cooler inside the shoe.
• Washable: OrthoLite insoles are machine washable, coming out like new every time while maintaining all of their performance benefits after washing.
• Lightweight: OrthoLite insoles are lightweight, enhancing the performance of the shoes with airy comfort.
• Moisture Management: The unique open-cell structure of OrthoLite insoles creates a moisture management system, helping to move moisture away from the foot to provide a cooler, drier, healthier shoe environment.
