I'm a little embarrassed, but I have bought three different colors of this shoe. I started with the yellow after I fell in love with it at a store. I bought it at a a fancy shoe store, not amazon, and wore it for field work. Due to really tough field conditions and wearing in all weather including heavy rain, I wore through them and then bought another pair on amazon in another color. I later found that green was reasonably priced so I picked up a third. I have owned yellow, blue, and green. Yellow and green are my favorite and give me that 'happy feet' feeling every time I look down. These shoes are perfect because they aren't boring but are comfortable and have a faintly vintage, well made and thoughtfully designed feel. I bought 7 and found I had to wear them a little to loosen up the tight parts, but no big problems or blisters. 7 is my regular size. I also got a heeled version of this shoe that I am in love with.
