I wouldn't use doc martens or any other boot with laces. Look for harness boots, if you can find one with a round toe, you could cut the straps off. It's got a similar silhouette and the same height. It's missing the cut out details and has a larger sole, but I think it's the way to go. As for the pants, with the exception of some really hard to spot seams around the knee area, I think these ones could be done with some wool poly blend dress pants.
