UN felt thermal insoles for boots size 37, model BHP WT 2052 are designed to improve warmth and comfort inside closed footwear. Made from dense felt, these insoles provide additional thermal insulation and light cushioning to reduce cold transfer from the ground. They fit into boots and winter shoes where extra insulation is required without significantly altering shoe volume.

Advantages

The felt construction offers effective thermal resistance while remaining breathable and flexible to conform to the shape of the foot. These insoles are lightweight and thin enough to be used in a range of boot types, from everyday winter footwear to work boots. They also provide basic cushioning that reduces direct cold contact and helps maintain a more stable foot temperature in low temperatures.

Suitable for

• Everyday winter shoes and boots
• Work footwear used in cold environments
• Outdoor activities such as walking, light hiking, and errands in cold weather
• Shoes that need additional insulation without major fit adjustments

Key specifications

• Material: dense felt for thermal insulation and light cushioning
• Size: EU 37 fit for corresponding boots and shoes
• Form factor: full-length insole designed to be trimmed if necessary for precise fit
• Thickness: thin profile to retain internal space in boots while adding insulation
• Compatibility: suitable for closed boots and winter footwear

How to use

Remove the factory insole or place the felt insole on top of the existing insole depending on the available space and desired warmth. If necessary, trim the perimeter carefully using scissors to match the interior shape of the boot, starting from the toe area and checking the fit before cutting further. Insert the insole flat and ensure it lies evenly without rolls or creases. Replace or air out the insoles regularly to maintain freshness.

Usage recommendations

For best thermal performance, use the felt insoles with well-fitting boots that leave limited hollow space around the foot. Avoid prolonged exposure to moisture; dry boots and insoles thoroughly after wet conditions. If combining with orthotic or specialty insoles, check fit and comfort before extended use.
