Got these for one of my sons as a gift.  They are very well constructed, and look like they will last a long time.  Sheepskin is adequate certainly, but not quite as thick as Uggs, which are priced more than double.  Unfortunately, had to return them, as they were sized much bigger than I expected.  They are longer and wider than the regular size 12s my son wears.  Maybe it's intentional for comfort, but for a narrow foot, it's more room than needed.  Average to wide feet would be in heaven in these slippers.
