Updated: March 18th 2018. I have giving this a 3 star now because the sole is coming apart. I have never worn these boots outside and I only wear them indoors. I have barely had them 3 months and the sole is coming apart. Not happy.

This item is as good as UGG> Being Australian I hold a grudge against UGG Australia because they patented a generic word used by Aussies for decades to describe sheepskin boots. Sheep skin boots Never had any brand-name on them when I was growing up and you could buy them at the Victoria Market on Saturday or Sunday for dirt cheap.
The Emu product is great however I do have to wonder at the stitching on the heel and on the front ankle area. It is a bit tight and it does rub against the skin which is a little uncomfortable.
The rubber soul of the footwear is different and feels unusual to walk around however I suppose it is a matter of getting used to.
I wear a 5.5 to 6 shoe and I purchased a size 5. Your are supposed to go a size or half size smaller because these sheepskins stretch.
It was very tight to begin with but it is slowly adjusting to my foot and calve. And by the way your not supposed to wear socks with this type of footwear. The lambswool is excellent quality and feels amazing.
I really like them and am very happy with the product.
