## Summary description

Felt insoles Lahti Pro in a 1-pair set, size 39, equipped with a foil thermal layer. Designed to be inserted into shoes or boots to provide additional insulation, reduce cold transfer and improve comfort in cool conditions. Suitable for everyday footwear, work boots and outdoor activities where extra warmth and cushioning are needed.

## Long description

Lahti Pro felt insoles with foil, size 39, feature a three-layer construction combining non-woven felt, foam and aluminum foil with a total thickness of 6 mm. They provide increased thermal insulation, absorb moisture, and help adapt the insole to the foot shape while reducing pressure on the sole. Designed for cooler seasons, these insoles are suitable for autumn and winter footwear.
Advantages

Non-woven felt offers cushioning and durability, foam improves comfort and conformity to the foot, and the aluminum foil layer reflects heat. The insoles reduce foot pressure on the ground and facilitate a better fit inside shoes.
