I am picky and researched boots for a while before deciding to give these a try (based on some great reviews I had read about their comfort).  This boot is THE most comfortable boot I have ever put on my feet!  It really felt like a slipper trying it on right out of the box.  I am a loyal ECCO wearer so I am familiar with their quality and excellent fit but this boot still surprised me.  I just love it!  It's totally waterproof yet stylish at the same time.  I am 5'6" w/ fairly long legs and the boot hits me a couple of inches below the knee- just where I wanted it too.  What I like most is the large stable bottom.. no heel to deal with.  I really want the brown ones now!
My only CAUTION:  I had read this in a review... it runs 1 full size small.  I wear an ecco 40 all the time.  I ordered a 41 after reading others' experiences and I am SO glad I did!  I have enough room to comfortably wear nice thick warm socks or thin dressy ones but if I had gotten a 40, they would have been too tight.
