Why mess with what works.
These aren't so premium because they take minutes off your TT or anything... they're premium because they allow you make a small lateral movement of your cleat if center-neutral doesn't work for you. I got some for my bulky winter boots that otherwise would lightly rub my cranks. Problem solved. Additionally, they span the breadth of the slots in an SPD shoe so that your platform is wider than with the ultra-narrow 'race' cleats that come stock with the new Eggbeaters, which place all your weight on just the center bridge of the outsole that exists between the slots. I've heard reports that these engage the new eggbeater pedal slightly less easily than the race cleat, but haven't experienced any problem myself.
