I have the Spring Step Burbank in the red and love them - so comfortable and so many compliments when I wear them.  I just received the Chino in olive and have not had a chance to wear them, but the 3 stars come from 2 reasons: 1. in trying them on, they seem a lot shorter and tighter than the same size in the Burbank but that may change with wear and 2. The olive color which seemed to be a dark green is more like a dark brown, so while I will keep them (for me, a hassle to return), they are not what I expected.  Maybe, as someone else said, the leather will change with age, and it will look more olive.

Update - November, 2011.  They really are an olive color, but it only shows that way in the sunlight or other light.
