There is a myth about Ghurka soldiers, fighting for Britain, who crawled along the ground feeling the laces of the soldiers they came across. British soldiers normally laced their shoes by straight or bar lacing techniques. The Japanese troops used more of a criss-cross pattern.
Criss-cross laces meant the difference between life and death.
So I guess the moral of this story is: if you notice any Ghurka soldiers feeling your shoelaces- and you tie your shoes like every other normal person- watch your back.
