Bought these in Jan 2012, wore them until probably mid-April - 3 solid months.  Took them out this fall with the chilly weather and noticed the heals were completely worn through, and where rubber sole connects to the leather toe it was splitting open.  As an over-tired and very busy mom, I wanted to try to return them, but it just hasn't happened.  Here I am now in Jan 2013 and they are just embarrassing to be seen in.  The front of one is completely broken through now.  They are perfectly warm and comfy and love the look, so I'm that much more disappointed.  Broke down and grabbed a $12 pair of slippers from Costco to have on standby for the final explosion.  We don't have a lot of money, so this purchase was a little painful but I thought of it as an investment.  Sigh.  And for the record, I don't wear them outside or play basketball in them or do anything outside of the norm.  Just wear them around the house to keep my piggies warm.  And I'm not hard on shoes.
