Ian Fieggen revolutionized the shoe world with the advent of his Ian Knot. Feiggen's passion for knots may seem funny at first, but after learning his Magnum Opus your shoes will never become untied again. Runners know that untied shoelaces can be dangerous and cost you precious time during a race. So leave the Granny knot behind and watch this tutorial. I promise there is no "bunny going around the tree" metaphor involved.
