quantify the benefits that are given by the shoes, and then keep everyone within those bounds Which is what they're trying to do. You can't make everyone wear the same shoe, because Shoe X may work better for you and Shoe Y may work better for me. (Then you add the complexity may be that Shoe Company Y may be willing to pay you more money.) But the downside is that it's lowest-common denominator technology. Every time a manufacturer comes up with a game-changing idea, it's "unfair" because they've figured out a way to give more benefit in a way that no one else has, yet.
