Here's a site on lacing and tying shoe laces. There are tons of ways to lace your shoes and a bunch of ways to tie them. The guy lists the pros and cons of each method. Breaks shit down to visual and functional aspects. I thought it was stupid at first but then took a closer look. Its very well laid out and presented information even if it turns out the stuff doesn't work as advertised. I figured I'd give some stuff a try and see.
