I had to have a low heel, and I'm not a big fan of shoes, so it had to be comfortable and easy to get on and off.  I have two pairs of Clarks for work, and not only are they comfortable, but I'm not sure they will ever wear out (a little polish and buff and they look new, year after year).  These were comfortable from the first time I wore them.  With or without socks, no blisters, rubs, or aches.  And they look great.  Clarks has never let me down.....
