UN Protective Felt Thermo Insoles for Boots size 45, model BHP WT 2137

UN Protective Felt Thermo Insoles for Boots size 45, model BHP WT 2137 are insulating felt insoles designed to fit size 45 boots. Made from dense felt material with thermal properties, these insoles reduce cold transfer from the ground, add cushioning and improve overall comfort in work and outdoor boots. They are intended for colder environments where retaining foot warmth and reducing fatigue during prolonged standing or walking are required.

Advantages

The felt construction provides thermal insulation while maintaining breathable properties that help manage moisture. The insoles add a layer of cushioning that evens pressure distribution across the sole, reducing discomfort during long shifts or extended walks. Their size and shape are suitable for standard boots and can be trimmed if minor adjustment is needed for a precise fit.

Suitable for

• Work boots used in cold warehouses, construction sites, and industrial environments
• Outdoor boots for hiking, hunting, and winter activities
• Everyday boots worn in cold climates to increase comfort and warmth

Key specifications

• Material: insulating felt
• Intended shoe size: 45
• Function: thermal insulation, cushioning
• Edge finish: cut-to-fit friendly for minor trimming
• Breathability: moderate, suitable for extended wear

How to use

Insert the insole into a clean, dry boot with the felt side facing upward. If necessary, remove the original insole before fitting. Check the fit by standing and walking a few steps; if the insole is slightly too large, trim the edges carefully along the boot's existing insole outline for a tailored fit. Ensure the insole lies flat without folding or bunching to maintain comfort and insulation performance.

Usage recommendations

For best results in cold and damp conditions, keep boots and insoles dry between uses and air them after wear. Replace insoles periodically if they show signs of compression or wear that reduce thermal properties or cushioning. Avoid machine washing; clean with a damp cloth and let air dry.
