Cut to Size Thermal Insole with Wool and Aluminum Base.

Cold feet during winter? Add the Cut to Size Thermal Insole to your running shoes or winter boots and feel instant warmth. It’s thin, soft, and built for extreme cold, making it ideal for outdoor walks, work, or travel. Despite its lightness, it delivers powerful insulation that keeps your feet cozy even during the coldest days.

Made from 100% natural wool, this insole helps maintain an ideal temperature and prevents your feet from getting cold or damp. The upper woolen felt layer traps heat and offers excellent softness. Beneath it, a recycled felt layer locks out moisture while providing great breathability. Together, these layers balance warmth, dryness, and comfort perfectly.

The aluminum base layer reflects body heat back toward your feet and blocks cold air from entering. This clever combination prevents heat loss and protects against dampness. As a result, your feet stay warm and comfortable no matter how low the temperature drops.

Every step feels supported thanks to the soft wool surface that cushions and reduces pressure. The lower layers add strength and prevent wear or fraying, so the insoles last throughout the season. Whether you’re walking, hiking, or working outdoors, you’ll feel steady warmth and reliable comfort.

Because it’s a cut-to-size design, you can easily adjust it to your footwear. The insole fits European sizes 34 to 45, so trimming it to your preferred size takes only a few moments. It adapts perfectly to boots, sneakers, or casual shoes without slipping or bunching.

Made from renewable and eco-friendly materials, this insole combines sustainability with comfort. It keeps your steps light, warm, and environmentally responsible.
