Comfortable right out of the box. Wore today for the entire day and have no complaints. The leather is very nice and the workmanship is exactly what I expect from Clark.  I ordered up 1/2 a size to allow for insoles if needed so the heel area is a bit loose, but not uncomfortable. They are dressy enough for dress pants  but would look equally good with jeans.  The side zip allows for easy on and off. The toe box is roomy without being chunky.  I think I may order a pair in brown!  These are a nice all around boot and I would definitely recommend to friends.
