Designed to make all outdoor activities more comfortable, 3M™ Thinsulate™ Thermal Insoles are the perfect companion to virtually any footwear. The insoles each feature four levels that work together to create a more comfortable environment for your feet. The top layer is made of an abrasion-resistant material that wicks moisture away from your foot and reduces odor with its antimicrobial technology. The second layer is made of foamthat conforms to your foot for custom comfort. Thinsulate&trade insulation makes up the third layer, giving your feet exceptional warmth, while the bottom layer delivers great shock absorption and energy return with additional antimicrobial protection and moisture wicking performance. These insoles are especially helpful to cold-weather hunters, allowing them to stay out longer despite bone-chilling temperatures. Color: Red/Black. Imported.
