If you do end up in shoes you need to tie. The issue may be that when you tie your shoes the knot is a granny knot instead of a square knot. To make the square knot,

take both strands Pass left around right Make a loop with the left and wrap the right lace over and around and pull through as a bow.

You can check if you got it, depend on if the bow is straight across side-to-side. If the bow ears are crooked or up-down, it is a granny knot. You can undo the last step and wrap the opposite direction. Hope this helps!
