I decided to get these slippers because my wife got a pair of the Emu Stingers and I saw how comfortable they looked. Th slippers are quite comfortable, but they do not seem to be made with the same quality sheepskin as the boots are made from... it is not as plush. If it matters to anyone these are not Australian made like the boots, they are Made in China (what isn't made there these days). If Backcountry gets the Emu men's Stinger Mini's in stock, I will be considering returning these slippers and exchanging them for the Stingers as they seem like they would make a much more comfortable slipper.
As for the size, I am typically between an 8-9 depending on the brand of shoe. Everyone on here that said the slipper ran on the small side had me nervous but I went with an 8 and they are actually a little loose (but a smaller size wouldn't fit.) So IMO I would say they are true to size.
