I've been looking for a flat, comfortable, zip-up boot for awhile and finally found it when I came across the Quebec boot.  It's a soft, flexible, light boot and just the break from my tough, hard-leather motorcycle boots.  I love the shape of the foot and the quality of the materials.  The lining fabric is even cute.  The only cons, the zipper is on the OUTSIDE of the boot making it a little difficult to zip up, and there's a velcro panel that gets caught on my tights.  Other than that, these are great boots for the price available here!
