Insoles lahti pro Felt with Foil — 1 Pair Size 41, felt top layer, foil insulation

Lahti pro Felt with Foil insoles, size 41, feature a three-layer construction of nonwoven felt, foam and aluminum foil with a total thickness of 6 mm. The layered design improves thermal insulation, helps absorb moisture and allows the insole to adapt to the shape of the foot while reducing pressure between the foot and the shoe sole. These insoles are designed for cooler seasons and provide extra warmth and comfort in autumn and winter footwear.

Advantages

The three-layer structure combines a durable nonwoven felt layer for insulation, a cushioning foam layer for comfort and pressure relief, and an aluminum foil layer that reflects cold and enhances thermal performance. The 6 mm thickness balances insulation and fit while the materials wick and absorb moisture to help keep feet drier. The insole can be trimmed to fit and helps improve overall foot support inside existing shoes.

Suitable for

• Everyday autumn and winter shoes and boots
• Work shoes requiring extra insulation and cushioning
• Footwear needing quick insole replacement or size adjustment

How to use

Remove any existing insoles if necessary, place the lahti pro Felt with Foil insole inside the shoe with the felt side up and foil layer facing the sole as intended. Check the fit; if trimming is needed, mark the outline using the original insole as a template and cut carefully. Replace insoles when they show visible wear or reduced cushioning.

Usage recommendations

Use these insoles in closed footwear for autumn and winter. Allow shoes to dry between uses to maintain insole lifespan; do not machine-wash. Trim carefully to avoid overly reducing thermal and cushioning properties.
