1. Untie the top two rows of holes of shoelaces, and then put each shoelace through a hole from outside to inside in a normal way.

2. Thread the shoelace from the inside out through the shoelace hole on the other side. Note here that this row can't wear the hole position symmetrical to that side, otherwise it will lead to different lengths of shoelaces on both sides. Don't pull out the shoelace completely, just leave it about this length, and the length should not exceed the tongue, otherwise it will be very ugly to expose the shoelace outside when wearing it.

3. Thread the other shoelace through the remaining hole, and thread the remaining hole as above. After these operations, two shoelaces will be left in the tongue, and then roughly adjust it.

4. Finally, you can see four shoelaces left in the tongue of the shoe. Put on your shoes, adjust them according to your own feet, then fix the shoe head, and fix the extra shoe head with the shoelaces of the upper.
