I really like these slippers. They fit nice and snug and the insole is contoured like a nice hiking shoe. They are a little tight at the top of my foot though and I had to buy a half a size big to be able to fit in them comfortably.

Update: 1-4-2013.

So I've had these slippers for a little over a year now and while I still say they are really comfortable and warm slippers they are absolutely shabby on the outside. After a few months I began noticing wear on the outside of mine. I sit at my desk a lot in the evenings with my feed crossed and I thought maybe the wear was coming from that but after a while they were wearing around the top where my pants leg rubbed them and began coming apart where they crease as I walk. They are to the point now where they look like absolute garbage and are pretty much falling apart though the inner part of the slipper is still together and comfortable.

I'll probably buy another pair soon to replace these and am considering getting a different version that has a nylon shell look to it rather than the wooly appearance that these have. I bought my wife a pair with the shell look and they are holding up nicely.
