Warm, soft feet make for a better night's sleep. The Heat Holders® Women's LITE™ Eileen Stripe Sleep Sock is 5x warmer than a standard cotton sock. Made with advanced thermal yarns that are long looped and intensely brushed, they're incredibly soft on the inside — trapping warm air next to your skin to keep your feet warmer for longer . A cozy stripe design makes them perfect for pulling on at bedtime. Non-constricting and gentle enough for sensitive skin, so you can wear them comfortably all night long. LITE™ socks are great for relaxed shoes like running shoes. Just drop in the washer for convenient care.
