First thing is tighten up the lacing over the top of the shoe. Then put the left lace over the right one and under (called an overhand knot).
Then form a loop with your right hand like in the photo above. Hold the left hand lace in your left hand...and...
...pass it under the loop and around the front. See the orangey highlighting above. The green bit is what I'm gonna call THE HOLE. The red lace that goes over it, I'm gonna call THE RABBIT.
Phew, that's the first really fiddly bit done! Now, grab that rabbit with your right hand and the other loop with the left hand, as in the photo above.
Pull them, being careful not to let the ends of the laces pull through. Can be fiddly, but don't worry, it will come with practice!
