I received the slippers for a Christmas gift.  They are extremely comfortable and warm.  They were great...until the wool started to pull off of the rubber sole.  I contacted the company about this, as they are only 6 months old.  They did not reply to my email.  I was hoping that they could replace them, as I do not think this is normal for them to only last 6 months.  Needless to say, I will not be buying another pair.
