Afraid not, Harbormaster...Look at the heels. Cavalry boots, the ones most often associated with tall boots in this time frame, would have had tall heels to keep them from slipping through the stirrup. The same kind of heel can be seen on authentic western "cowboy" boots from the western expansion for the same reason.
Now those boots in the picture you posted would be better if they were turned up again, but still need a tall heel to be authentic...and nice knees, by the way...
