A lot of the heat is lost directly through the bottom of your foot. Acton® boots are built with several insoles, each serving a specific purpose waterproofing, thermal insulation or absorption. Furthermore, ACTON® winter boots are made of natural rubber of superior quality offering thermal insulation, great flexibility, adherent outsoles and 100% waterproof.

All of Acton® 's liners contain 100% virgin wool. It is made of three complementary materials which create a revolutionary system "triple-layered", ultra-efficient. Here are those three materials:

1. Polypropylene
This hydrophobic interior layer absorbs, evacuates and evaporates dampness away from the foot and to the outside in no time.

2. The Winning Team: Wool & Polypro
Wool breathes with your body and supplies appropriate levels of insulation according to the temperature. The polypro's fiber draws dampness away from the foot to the outside through Metaltek® .

3. Metaltek®
Through its reflective properties and its tiny pores, this exterior layer keeps the cold out, allows dampness to evaporate and keeps body heat to the foot.
