I've worn a size 12M for fifty years. These are tight, even barefoot. I will not be able to wear them with socks. I hope they stretch out some. Quality of the product seems good. I recommend this product, but be careful on the size.They are extremely comfortable. I wear them both indoors and outdoors. I get many compliments on their appearance.Seems to be holding up well, we really like these. The lining hasn't matted down much in almost a year, and it's very comfortable and warm. Great for walking around in the house or on hard surfaces outside, good traction on slick surfaces in an emergency.Ordered a wide and it fits like a wide!!! Also….Great Quality & Comfortable!!!Made in Vietnam, not Australia, to my disappointment. I will have see how this hold up.My husband has purchased several pair of these same slippers over the years. He usually extends the life of the slippers by purchasing replacement Ugg inserts, but eventually he starts to wear down the sides of the heels. He suffers with neuropathy in his feet, so having slippers that are soft and cushy is extremely important. These slippers have never let him down.These are my husband’s favorite slippers. This is his second pair and he wears them every day. His first pair lasted well over 5 years. It is nice that you can replace the insole to extend the life of the slippers as well.Keeps my feet comfortable; not too warm, not too cool. Durable leather and cushy shearling.I started wearing slippers a few years ago (it comes to us all) and have tried many brands ranging from about £40 to over £100. I always buy genuine sheepskin as it is a natural product and your feet never smell in sheepskin. I am aware of all the hype around ugg boots so thought i would try these - they were over £100 but for strange reason, the exact same ones in black were only £71. I guess that is because black is not the iconic ugg brown? Anyway, not bothered about the fashion aspect and not caring whether i’m wearing iconic colours or not, i sent fir these. I am a size 9 so ordered size 9. As expected, they felt tight (as all good new sheepskin slippers do) but experience told me to keep them on. They softened to my feet in about an hour and fitted perfectly. I am stunned with the comfort of these slippers, they are absolutely sublime. I actually look forward to getting out of bed now so i can put them on! By far the best slippers I have ever had. My next ones will definitely be ugg....not sure how long these will last but they look like they will last a very long time as they seem extremely well made and robust.My last pair of UGG slippers lasted years but this pair are near the end of their life within weeks. The wool linning that provides the comfort and also ensures the slippers do not smell of feet has all but worn out from the sole. In may last pair that took years to happen -not weeks. I might as well have just purchased cheap supermarket slippers.I can only assume that these are fakes as none of my other UGG shoes are of this bad quality.This is my first pair of Ugg slippers & the quality & make is great. They are very warm & would be very comfortable, but, after reading the reviews & some people saying to order the next size up & some saying to order your own size, I decided to order my own size 8UK. They arrived in a couple of days & looked amazing all wrapped nicely in the Ugg box. On the box it said UK size 8, perfect I thought. I took them out & tried them on. A bit tight I thought, but after reading the reviews & people saying they need a couple of days to break in & they fit perfect, I thought they will be fine. Well after a week of wearing them, they are still tight & hurt after wearing for to long, the wool inside has given a little, but for the money paid I wasn’t expecting this. Then just today I found the sizing label inside the slippers them self, I read it & it says UK size 7 so this is why they are so tight. But now after wearing them for a week I guess I can’t return them, even though it’s there fault putting size 7s in a size 8 box. Not happy with the company, but the slippers would otherwise have got 5 stars.They are amazing slippers, this is my second pair, the first pair I had was to snug a fit I wore them all year round for two and a half years. I have bought a size larger and they are amazingly comfortable. I recommend you definitely get a size larger. I have purchased the shinny leather pair which enables me to give them a polish when needed. My original pair of Ascot slippers are two tone suede leather which are very are well worn and 'stained' quite badly due to constant use and hard wear, particularly during my having to clinically shield over past 6 months ! My original pair I purchase from an Ugg outlet store but I have purchased the latest pair from Amazon as they were offering the best price, 30% less than the recommended Ugg cost price! My new purchase is in readiness for the winter when I am sure the price will rise again.Tight fit currently but having had sheepskin fur lined boots for many years(Just Sheepskin), they are always tight first but soon bed down. If they are not tight at first they are probably too big a size. These are superbly made, comfortable to walk on and a really nice rubber type sole. I know if I look after them they will last a good while. Very happy with these UGG's - the quality is great and the fit is as expected - I take a size 10 shoe (really I am a 9 to 9.5 in length with wide feet) and this size 10 UGG slipper is the correct size for me.
