I love my 6-year old Ecco ankle boots and so I decided to try these shoes in Moon Rock.  First of all, the color rocks!  I have received compliments.  But importantly, they fit like slippers.  Very comfortable, no chafing.  The only problem is that I wear a size 7M shoe and I ordered the UK size 7/7.5.  They were too big.  I returned them for the 6/6.5 size, which fits much better - with or without socks.  I thought they'd be snug but they are still quite roomy.  So I suggest you order a size smaller than your shoe size.
