This is my first Acorn product and I can't say enough about the comfort as well as fit and finish.  Sole cushioning
is superior, fit is spot on, the sole gives just enough traction and the detailed finishing is flawless.  But the most important feature
to me is warmth since I always have cold feet.... these are very warm but they do breathe and always feel comfortable, whether inside or out on the patio.  I've had these over a month and have seen no deterioration in the above initial impressions.  Very pleased with this purchase.

Update 9 months later: I've never had slippers that lasted two seasons, until now.  Halfway through my second year of regular wear and they still feel like new.  The ample cushioning is still roughly 90% of day 1, which has been a pleasant surprise since most foams break down rapidly with use.  Outer sole shows no deterioration and most importantly to me, the stitching shows zero breakdown and the entire shape still looks like day 1.  I can't imagine ever buying any other slipper based on my use so far, but since they don't appear to be aging, it may be a while!
