The boots I bought appeared to be original UGG boots but once I received them and saw the zipper... I was not sure they were authentic. Thanks to the MyCozyBoots team for responding to my initial review with evidence of the authenticity of the Abree II Croc boots. Revised review: They are comfortable and are my second pair (1st pair purchased elsewhere). I was laready able to test them out in the snow and the cold as we had a snow storm last week in NY. They were perfect for the sleet, snow, rain and ice. The fact that they are authentic UGGs is a wonderful bonus.
