Goerge,
I believe the mountian troops used wrap leggings before the war, the reason the infantry used the Marsch Stiefeln was because of the wet environment, the leather high topped boot could be waxed or oiled to make it water proof so they worked like a rubber boot for marching through the country side, when they started trench warfare, they found this type of boot was prone to gather stones and dirt in the wide tops, I have seen a photo where a soldier has pulled his trousers over the top of his boots to keep the debris out of his boot. On a side note, this is how you can tell a real cowboy from a dimestore cowboy (aloso know as a goat roper) only a dimestore cowboy will tuck his pants into his boots.
