Sheepskin Slippers - All Natural Comfort for Any Season - Slip your bare feet into a pair of Cloud Nine sheepskin slippers, and whether it is summer or winter you will experience a level of comfort that is nothing short of sublime. This is because sheepskin fiber is naturally thermostatic. Thus the interiors of your Cloud Nine Sheepskin Slippers by Cloud Nine will stay at body temperature whenever you wear them ensuring that your feet stay warm in the winter and cool in the summer. If you have perpetually cold feet because of diabetic foot problems or another foot condition that hinders blood circulation, Cloud Nine sheepskin slippers may be a better and safer method of keeping your feet warm than a hot water bottle or electric blanket.
