Safety Shoe Insoles Kaps Filc Comfort 011820, felt insoles, uncolored, sizes 35–46

Kaps Filc Comfort 011820 felt insoles are uncolored replacement insoles for work and safety shoes, available in sizes 35–46. Manufactured from dense felt, these insoles deliver thermal insulation, cushioning and a more secure fit inside various types of safety footwear. They are intended for daily use where added warmth, shock absorption and comfort are required, including industrial environments, outdoor work and cold conditions.

Advantages

The dense felt construction provides reliable thermal insulation while remaining flexible enough to conform to the shape of the shoe. These insoles absorb part of the impact from walking and standing, reducing pressure on the feet. Their neutral (uncolored) finish keeps them compatible with different shoe linings and reduces the risk of color transfer. Available across a wide size range, they can be trimmed or selected to match common safety shoe sizes for improved fit and wearability.

Suitable for

• Work and safety shoes used in industrial or construction settings
• Outdoor footwear for cold-weather tasks or fieldwork
• Everyday use by workers who need extra cushioning and thermal insulation

Key specifications

• Material: dense felt
• Finish: uncolored (neutral)
• Size range: 35–46 (trim or select appropriate size)
• Primary functions: thermal insulation, cushioning, improved fit
• Intended footwear: work shoes, safety boots, outdoor footwear

How to use

Remove the existing insole from the shoe if present and place the Kaps Filc Comfort insole inside, ensuring the shape and length match the shoe’s interior. If necessary, trim the edges carefully along the shoe’s original insole outline to achieve a precise fit. Position the insole flat and smooth any folds or creases before wearing. Regularly inspect the insole for compression or wear and replace it when cushioning or insulation performance declines.

Usage recommendations

For best results use one pair per shoe and select the correct size for a snug fit. Allow damp insoles to dry naturally at room temperature; avoid direct heat sources. Combine with appropriate safety footwear to maintain the shoe’s protective functions and to ensure comfort during prolonged standing or walking.
