Why do sports shoes have two small holes?

It seems useless, but two small holes on the sneakers have great use, but few people know.

When tying the shoelaces, did you notice that the two adjacent holes on the top have two tiny holes? You don't know what it used to do and completely forgot it ever existed.

If that's the case, you're wrong, those two small holes have great uses. After putting all the holes in the shoe, do not stop, put the ends of the shoelaces into two small holes on either side as shown below.

The final step: you put the shoelace on this side of the strap on the other end of the cord and pull it tight as shown in the picture below. After doing so, make sure your shoes will be smooth and fit with your feet , running freely without fear of shoes going out.
