I've had 4 pairs of this slipper in different embroidery patterns, and I'm a fan.  They're instantly cozy from the moment you slip them on in the morning, and no plastic insole to be cold or unpleasant.  My pairs get fairly heavy use because I wear them as house shoes on and off during the week.  I'd say they're good for about two or two and a half years, with a couple of pair going at the same time.  The sole has good traction, and is suitable for a trip to the garage, basement, laundry room, even out on the driveway to get the paper.  They're not designed for outdoor use, but a little cheating once in awhile won't ruin them.  It's a good slipper, better than many others -- that's why they cost more.  Plus, they look snazzy.
