I was very excited to purchase these shoes, as I had looked at the Mammoth Crocs in stores and the polar fleece of the Blitzen seemed like a step up in warmth and comfort.

My advice: if at all possible, do not buy these shoes online. Try them on in the store first because the sizes are really weird. It's not just that they are smaller than usual; it's that they are not a typical size and width. If you do order them online, be prepared to send them back to exchange sizes.

I took the advice of several reviewers and ordered a size larger. (I'd considered ordering two sizes larger, but just couldn't believe I'd be able to fit into a size 10 shoe when I'm normally an 8). The size 9 was small in the front--although my toes weren't near the edge of the Croc, they were cramped due to the thickness of the fleece. At the same time, the back of the shoe was too large and floppy and my heel kept sliding around as I walked. How the shoe could be both too big and too small, I don't know, but I assume it has to do with the liner and the length of the shoe.

These might be good for someone with wide feet, but I would not recommend them for someone who usually wears a size 8B. From now on I'll stick with another type of Croc.
