If you have trouble with toe nail trauma (all chipped for instance) check out heel lock lacing. It will prevent your toes to hit against the front of the shoes.

One example here [0] for running shoes but it's useful also for normal walking. Ian of course has his own entry about this [1]

I found this to be incredibly helpful for blister prevention. Only downside is your laces have to be pretty long since this takes up a couple more inches on each side.
