No more cold feet! Micro Flannel® Heated Foot Warmers provide luxurious warmth and comfort at home or in the office. The electric heating pad gently warms your feet while you enjoy the cozy, ultra-soft feel of the Sherpa fleece sock. Prioritizing safety and convenience, this foot warmer has an 8-foot detachable cord with a 2-hour automatic shut off. Machine washable for easy care, the outer Micro Flannel® bootie and the inner Sherpa lining easily come apart and will not shrink or pill in the washer and dryer. Designed to last, the printed Micro Flannel® outer slipper retains its shape and never fades. This product is ETL tested and certified.
