Ian's Shoelace Site
I'll vouch for the "Ian Knot". Throughout my life I had to double-tie the classic shoelace knot or else it would come loose a some point during the day.  Then I tried the Ian Knot. It is significantly faster and easier.  And, now I have some laced shoes that I just slip on because they stay tied for weeks instead of hours.http://www.fieggen.com/shoelace/ianknot.htm
