After nearly 11 years in my old Birkenstock shearing lining slippers, I had worn them completely out & needed something new. I've never had a pair of UGGs before and really hadn't thought of them before but wanted something to wear around the house that had a few things:
Lined with warm fur inside.
Hard sole on the bottom for running to the mailbox/quick car pickups & drop offs of my kids to school.
Earth tone color for hiding dirt & messes from the kitchen.
Slide or clog style, no back or ties, not tall or hard to put on(no hands necessary)

These fit the bill. They are warm & stylish. A bit snug at first because of the fluffy lining but I know that will compact down eventually. The bottoms are very flat, which kind of bugs me right now, but I was used to birks with an anatomical footbed. I don't know if all UGGs are so flat, just be aware that they are. The soles have good tread for a slipper, raised & seeped areas for traction. I have no idea how well the knit area on the outside will wear long term. It's very sweater-like, so I suppose snags can happen.
They fit pretty true to size. I am a 9.5 but I got a 9 because the 10 footbed really seemed to stick out quite a bit behind my heal. And since I knew the lining would compact, I felt that the 10s would eventually be too "floppy" feeling after they stretched a bit.
I recommend these as a good house slipper or even a running around town slipper.
A bit pricey, but aren't they all? I hope they last me half as long as my birks(although 10 years would be nice!)
