The more air a material traps in a given space, the greater its insulating value. Because the microfibers in Thinsulate™ Insulation are finer than other fibers, they trap more air in less space, which naturally makes it a better insulator. CLEANFEET® odor control treatment is a game-changer in the footwear universe. This patented technology doesn’t just help odour - it actually works to prevent odor before it starts, CLEANFEET® stops odour dead in its tracks. Safe and natural, CLEANFEET® is a natural and safe method of controlling odour, guaranteed for the life of your workboots. Cambrelle® fabric lining provides superior moisture management, comfort technology and abrasion resistance. These elements are fundamental for all-day performance.
