I could tighten up the straps, but as long as my foot stays in the shoe, I don't see what is to be gained by having tight shoes. In fact, I think feet benefit by having additional circulation with a looser shoe.

Fast group rides and racing are another matter, and there are good reasons to go a little tighter there.
