Very surprised how warm my feet are in these slippers!  Have been wearing Dearfoam booties past few winters; but since my feet were still frequently cold, I decided to try these Acorns as they were highly rated.  Happily my feet no longer feel cold in the evenings.

The sole is supportive, flexible, and comfortable - which is vital to me due to problems with my feet.  I am able to wear them all day without discomfort.

Only change I plan to make next time I order will be to order a larger size.  Several reviews stated Acorns run large so I ordered a smaller size (which I always did with Dearfoams too.)  However, the right slipper is bit snugger than optimal.

Also, material and color are ideal for me... they blend perfectly with the fur from my three black & silver tabbies and don't look too hairy between cleanings.  =)
