This heartwarming Father's Day card shows the image of two pairs of shoes: one, a worn pair of brown work shoes; the other a pair of bright red and white sneakers. One sits on top of the other, as a gentle reminder that while you may never fill his shoes, if you're able to come close, that's all that matters. Whether you have kids of your own or not, this touching greeting from a son to his dad will make him feel loved and remembered not just today, but all throughout the year.
