"I bought these for my girlfriend's birthday, and although she's only worn them once, they appear to be very soft, durable, comfortable and great quality. Unfortunately they had to be returned since they were 18 sizes too small.
Are Australians only like 4 feet tall? Because these were at least a size and half too small. She normally wears a 10 or 10.5, so I got 11s and they were still too small probably by a full size. I'm ordering a 12 and I hope they fit because that's as big as they get. If anything, slippers like these should be slightly oversized, not so tight they look like sausage casings.
If you're a half size, you may want to order 1.5 sizes up, unless you're Australian, then just order normally."
