Bring on the winter weather! Our adorable Nordic Blue Slipper Booties are the perfect antidotes to the frosty chill outside. With a bright, blue-and-red knit outer layer (100% acrylic) and a super-fluffy faux sherpa lining (100% polyester), they'll keep you toasty warm and cozy all winter long—and look great at the same time! Features a slip-resistant sole. Please specify size: S/M (fits women's sizes 5-8, men's 3.5-7.5) or M/L (fits women's sizes 8-11, men's 7.5-9).
