UN Felt Insole Thermo for Boots Size 47 (MPN BHP WT 2151)

UN Felt Insole Thermo for Boots Size 47 is a felt thermal insole designed to fit boots with a European size 47. Made to increase insulation and improve underfoot comfort, this insole helps reduce heat loss in cold conditions and adds light cushioning inside work or outdoor footwear. The product is intended to be trimmed if necessary and inserted under existing insoles or used alone depending on boot construction and user preference.

Advantages

The felt construction provides natural thermal insulation and distributes pressure across the sole for improved comfort during prolonged standing or walking. This insole is lightweight, thin enough to fit in most boots without significantly altering fit, and can be trimmed to size for a tailored fit. It is suitable for adding warmth to seasonal footwear and can complement waterproof or insulated boots to enhance overall thermal performance.

Suitable for

• Workers who spend time outdoors in cold weather and need extra insulation inside boots
• Hikers or outdoor enthusiasts using boots in chilly conditions
• Individuals seeking a simple, low-profile insole to improve warmth and basic cushioning
• Boot owners who want a trimmable insert to adapt to slightly different in-boot sizes

When it may not be suitable

This felt thermo insole is intended primarily for additional warmth and light cushioning; it does not provide structured arch support or corrective biomechanical features. Users requiring specialized orthotic support, high-impact shock absorption, or moisture-wicking technical liners may find this product insufficient on its own. Also, in very tight-fitting boots the added thickness could affect fit; trial insertion and trimming may be required.

Key specifications

• Material: Felt (thermal insulating fabric)
• Intended size: European 47 (trimmable to fit)
• Primary function: Thermal insulation and basic cushioning
• Compatibility: Designed for use in boots and similar footwear

How to use

Remove the existing insole if needed and place the felt thermo insole inside the boot to check fit. If trimming is required, use the existing insole as a template: place it on top of the felt insole, trace the outline, and cut carefully with scissors. Insert the trimmed insole flat with the felt surface facing up and test the fit by wearing the boot for a short period. Adjust or further trim if necessary to avoid pressure points or changes to boot closure comfort.

What to consider before purchase

• Measure your boot internal length or compare with your current insole to confirm compatibility with size 47.
• Decide if you need arch support or medical orthotics in addition to thermal insulation.
• Check boot fit after adding the insole — some boots may become tighter and require trimming or removal of the factory insole.

Usage recommendations

For best results in cold conditions, combine the felt thermo insole with breathable socks and appropriate boot insulation. Replace or dry the insole if it becomes wet to maintain thermal performance and comfort.
