Tie a basic knot. Take both laces and thread one lace over the other and then pull them tight. They should form a knot in the middle of the shoe.
Make a loop with one of the laces. You should be holding the lace between your thumb and your first two fingers.
Use your other hand to wrap the other lace around the loop. You should be holding it over your fingers and around the loop. Wrap the other lace toward you rather than away from you.
Pull the shoelace through the hole to form another loop. You should use your free hand to pull the shoelace through. There should now be a hole between the looped shoelace and the wrapped shoelace. Pull the wrapped shoelace through so it comes through this hole.
Hold both loops and pull them tight. You should now have a nicely tied shoe.
