A tale of two soles
Sometimes, an idea sounds so good that it just won’t go away no matter how bad it is.
Below, I give you a pair of overshoes designed for Special Operations Executive (SOE) agents operating in South East Asia during the Second World War. They were intended to disguise footprints to fool the Japanese as, if they saw a big ole European bootprint in the jungles of Burma, Indochina etc, it would give away the fact that the Allies were poking around in the rear. The soles did not work very well in practice, however, as they were still very big, and awkward to use, akin to snowshoes.
Fast forward to the MAC-V-SOG groups of U.S. Army SF guys working behind the lines in VC country in the 1960s and I give you boots designed to leave traces that look like footprints of peasants and to hide the movements of the teams. They proved instantly unpopular because they provided no heel support and made walking a jungle trail on your tip toes very awkward, especially when you are trying to avoid contact with unfriendlies.
