The ladies sheepskin bootie is more like a warm living room with a toasty fireplace for your feet. The fleece lined collar flips up to prevent cold drafts from descending on your ankles and feet, keeping things thermally friendlier than any other shoe. It's great for everything. You can keep the Ladies Sheepskin Booties on all day around the house; you can go outside in cold weather or warmer temperatures just the same. All sheepskin is "Thermostatic" - which means they keep you warmer in winter and cooler in warmer temperatures. But Cloud Nine Sheepskin booties excel in cold drafty winters - keeping you extra warm.
