I got these because I didn't want to spend the money on super expensive UGG's but really wanted a pair of sheepskin boots. These were an amazing purchase for living in the snowy climate I do, because they have a thick bottom meant for traction and being outside. The rubber is VERY durable and not the thin bottoms that comes on the normal styles. They are already apparently waterproofed, but I sprayed them myself as well to make sure they would be safe going outside. I have worn them outside through puddles and slush and snow and they still look like the day I got them. Beware, they are heavier due to their soles being made for outdoors so they are not a lightweight sheepskin boot. Also, they felt a little tight the first couple times I wore them but now feel amazing. Some people have advised buying bigger sizes. I would not. They do stretch and would probably be too big if I ordered any bigger. Great purchase if you are looking for Emu's that can handle some weather.
