I came across a pair of boots today that I think are more accurate. The Jack boots arr too tall. I do understand that they can work, so I propose a level 2 boot. These are "Hunter Bay Black Waterproof Commuter Boots" They do have a zipper on the inside, so it would be easily concealed.
As you can see in the attachment, they match up better. I even found some jack boots by the same artist, so you can see the differences in source materials.
