ArcticShield® Slippaz are thermal foot coverings envisioned after the original ArcticShield® Boot Insulators. These EZ slip-on slippers provide optimal comfort and warmth, using Retain™ heat retention technology that captures and retains up to 90% of your body heat back to you. The Slippaz confirm to your feet and the fleece interior adds insulation to block the cold from reaching your feet. Cinch up the drawcord for a perfect fit every time. The silicone print on the slipper bottom provides traction, even on wet, slippery surfaces.
