First I place one shoe lace under my foot and pull.
I make a loop still having the lace under my shoe.
Next I bring the loop behind and under the straight lace.
Then I let the straight lace out from under my shoe.
Using my pointer finger I place the loose shoe string on top of the loop and under through the hole.
With my foot on the bow, I make sure its all tight.
And voila!! It is not as complicated as it sounds, and it can be done.
