For the cost these are great lounging slippers for around the house. I wear a size 8.5 my feet have normal arches and a more slimmer foot from say a side profile, but these have a lot of room in the medium. The style i guess is called a mule? So the back of the slipper almost feels like there is no real support to hold your foot in. It feels like a good half size bigger, so this M does say 8-9 and for anyone with 8 or smaller foot, this might feel big. The bottom cushioning is great, very soft cushioning feel. The gray fabric that i got is very soft inswide and feels a little more rugged outside and looks good. The bottom actually has a rubber like tread. For the cost, it's a great lounging house slipper and for the price is good value. So again, just remember if you are on the smaller size like 8 the M will feel big but again, for the price you might just want this to wear around the house so being bigger doesn't really matter.

Cutest slippers, price was the BEST and so very comfortable.

Fit well, very comfortable and a great value. Will buy again.

Very comfortable and warm

Loved these slippers for years

My Isotoners are sre comfy and warm! They fit great & I can even walk outside with on.

Perfect slipper…very well made. Would buy again.

The black pair's interior continually sheds. The pink pair has not shed much at all.

So comfortable and they have a sole that’s hard so you can wear them outside

I wish the foot bed would last longer. Very good price, colors and fit. I live in these at home.
