This Tamarac slipper is really nice, warm, and well made.  I like the bottome sole that allows one to wear the slipper outside if needed.

Note:I wear a 10 1/2 womens shoe and ordered an 11.  My toes touch the end.  I would say that the slipper runs a whole size small at least by my experience.

I have worn them around for a few weeks hoping that the sheerling would smash down and it has some-what.  Order a size up if you don't want your toe touching the end.
