NK's Silk Cotton Home socks were crafted with an around the house footwear concept. The outer layer is made of durable cotton and the inner lining of moisture-wicking, highly insulating, silk cotton pile. We also minimized the use of elastic for the ultimate relaxed fit. These super cozy lounge socks will envelop your feet in fluffy comfort while keeping them warm and dry.
