What do you think about Reebok EasyTone?

I've seen the ads in magazines.  I've thought about how nice it would be to "work out" without taking time out of my day.  But do these shoes really work?  Shopaholics Anonymous and Adventures in the Stiletto Jungle both offer favorable reviews.  Can't wait to try these for myself.  Reebok EasyTone, $109.99.
