The Ortholite 'O-Therm' insoles are a pair of shoe accessories for those who spend extended periods outside in cold weather to help them stay warm and comfortable at all times. The insoles make use of the brands new proprietary aerogel that is infused into open-cell PU foam to work in tandem to provide all-day comfort as well as heat insulating capabilities. The insoles come in at just three-times the weight of air and work by trapping warm air to keep the feet warmer for longer.
The Ortholite 'O-Therm' insoles were third-party tested where they were found to be 54% more effective than a breathable thermal barrier. The insoles measure in at just 2mm in thickness to ensure they can be used in a range of footwear styles.
