double+knots

A double knot is a knot tied over itself twice, and is often used in tying shoes. This continues the analoly of shoes and roads for life because in the poem just like how double knots don't come undone easily if you tie the life style the poets talking about down with double knots it won't come undone.

Needed to keep exploring the analogy and developing your ideas logically -- this gets confusing.
