Crocs for winter - great idea!  Winter Crocs with large holes in them - bad idea!  I admit that I did not read the description well enough.  It says the holes on the sides are fake.  That made me think that the designers used some logic and made the holes fake for winter conditions.  I'll still wear them.  The lining is to-die-for soft.  But any time it is raining or snowing, they will have to stay inside.  Where I live in southwestern New York, there aren't many non-summer days that are not snowy or rainy.  I hope this review helps you not make the mistake I made by not reading carefully.  If you just want them for indoors or you live where there is less precipitation, you should enjoy them just fine.
