How to tie the Swiss Knot, the only knot a trail runner should use

With winter weather, you may find that as your shoe laces freeze up they may not stay tied up, or afterwards your frozen fingers cant pry open the frozen laces.
This very simple shoe knot will stay tied up and just slips open with a gentle tug even when frozen.
You will find yourself only using this knot for all your shoes, after trying it out on your next trail run.
