Using a heat retention technology called RE-tain, ArcticShield now offers these Boot Insulators that keeps your feet and toes warm.  The exclusive RE-tain technology utilizes a multi-layered thermal barrier that captures and returns up to 97 percent of your body heat. This method is more effective than thick traditional insulations that only slow body heat loss. This cold-weather gear is innovatively thin and unbelievably warm.
