Depending on the kinds of footwear you wear, you might try simply doing something different than tying them.
I wear mostly sneakers, and when I got annoyed with tying them (especially one pair with laces that got untied so easily I’m sure there must be some kind of bad design award they could win) I started kind of weaving the ends among the crossing laces. Kind of like this: http://en.wikipedia.org/wiki/File:Black_Etnies_shoes_with_checkerboard_laces.jpg except that it doesn’t have to be that elaborate, and it’s not as obvious if the laces are of one color.
If done just right (in terms of tension) it will be loose enough to allow sliding your foot in the shoe, but tight enough to keep the shoes from slipping.

For sports and more dressy shoes, or if you just might want to stick to knots, try http://www.fieggen.com/shoelace/knots.htm
(Funny, I hadn’t even realized there are two ways of forming the loops, I think I do it either way by instinct depending on length.)
