Cloud Nine Men’s Sheepskin Booties take keeping your feet warm to a new higher level (literally!). The fleecy collar flips up over your ankles stopping drafty cold air in its tracks, keeping you warmer than any low cut shoe. That makes the collar a game changer all by itself. So, when the going gets cold, Cloud Nine Booties keep you cozy. They are a shoe, a slipper or a bootie for light outdoor use and maximum indoor comfort.
