I'm a big fan of Propet Women's Travelwalker's, and bought two pair in this particular style, because I know that they will be true to size and comfortable when walking for long periods of time.  Also, they are very attractive style wise, and I have received numerous compliments when I wear them.  I was, however, a little surprised to find that they are very light fitting, and afford the ventilation needed in hot weather, but I would have preferred more stability in the shoe itself...
