Only an observant viewer will notice that, in the scene where Forrest Gump is sitting at a bus stop, his sneakers are very dirty, but his shoelaces are completely white. According to the fans of the movie, the character wants to show that he is trying his best to preserve the gift from his beloved woman. Gump has been wearing these shoes for all these years and has done everything to keep them going.
There is another theory as to why the character acted this way. This time, viewers recall the words of Forrest’s friend, Lieutenant Dan, who taught him to always take care of his feet.
