Every now and then on Lifehacker I come across an article like this one: Ditch the Granny Knot to Tie Your Shoes More Efficiently. I'm not sure how much more "efficient" it is, but it does make more sense and looks nicer to tie a reef knot on my shoes. The only change I have to make is going over the loop rather than under it, but it's surprising how hard it is to fight the muscle memory of years of shoe tying.
