I got these cleats from a good friend last week. Thanks Björn!
Acquired a (almost) new pair of pedals PD-7400 from US last week, but the cleats were missing. These things are very rare, thus expensive as hell.
The nice thing about these cleats is, besides being oiginal Shimano and rare, that they more or less "click into" the pedals, but it is not a click pedal system. This is what makes the pedal and cleat system so popular among track racers, especially spinters. The cleat offers an additional binding function, next to toe clips/straps.
