These boot liners are made with top-of-the-line industrial felt, with a layer of Radiant Tex material, which aids in capturing heat and redirecting it back towards the inside of the liner.
The liners are extremely comfortable and long lasting, while managing the temperature and moisture surrounding your feet.
The wool used in the felt has the unique ability to absorb 3 times its own weight in water. The wool also has the ability to breathe, thus allowing it to naturally release the absorbed moisture while being ventilated when not in use.
