Great for wearing around the house and short walks to the mailbox.  They are not stylish at all, so I would never wear them out in public.  I have recently washed them (long overdue) and they seem to be holding up since.  I used a casual wash cycle.  They are great to wear in the winter time around the house as well.

I would also recommend at least 1/2 size up from your normal fit.  I would recommend them.
