I've had this happen once, and we resolved it by placing the gecko in a small Kitter Keeper (or any small container) with heavily moistened paper towels touching it on all sides (i.e. direct contact all over). After a few hours of moistening we carefully assisted the little guy with his shed. As long as you’re careful and go slow with the small parts (like toes), everything will eventually come off (even if you have to repeat this cycle a couple of times).
Of course there’s the underlying issue of ambient humidity. As winter progresses and we use heat more often in our homes, the air can become unusually dry - You may consider using a humidifier for a time.
