OrthoLite increases range of O-Therm material

O-Therm is claimed to be the most adaptable and high-performing thermal footwear material on the market.

Comfort footwear solutions specialist OrthoLite has announced that its ‘O-Therm’ thermal foam material is now available in a wider range of thicknesses. Previously limited to a thickness of 2 mm, O-Therm is now being produced in a range from 2 mm to 20 mm which, the company claims provides a more customisable cold block solution for brand owners, as well as the most adaptable and high-performing thermal material on the market for cold weather footwear solutions.

According to OrthoLite, O-Therm is reportedly the first and only aerogel-infused, open-cell polyurethane (PU) foam cold block solution that can be applied not only as an insole but also a Strobel layer or lining. The use of O-Therm is said to keep the wearer’s feet warmer, allowing them to stay outdoors longer, feel more comfortable and perform better.

“By offering footwear brands the opportunity to precisely select the thickness range to meet their specifications, O-Therm stands to become the market’s most versatile and standard-setting offering for cold weather footwear solutions,” commented Rob Falken, vice president of innovation at OrthoLite, “[allowing] brands to go further in developing the most precisely applicable and high-performing cold-weather footwear across a broad range of footwear categories, including outdoor, casual, work, ski and snowboard, fashion, and other outdoor sectors.”

Aerogel is reportedly the lightest man-made material, at just three times the weight of air. Air porosity of the material is said to be more than 90 per cent, and the low density of the material is claimed to enhance the performance of the shoe with lightweight comfort. The proprietary O-Therm aerogel is also being marketed as requiring no special handling or encapsulation while being exceptionally hydrophobic, thus repelling water and moving moisture away from the foot to provide a drier inner environment.
