Diadora shoes for Power Drive pedals

When you’re a collector of pedals systems from the 1970s, 80s and 90s, of course you want the Diadora Power Drive pedals. Not, because these are so good or valuable, but just to complete your collection. Pretty rare, so you can be satisfied if you’ve managed to get a nice pair (or even 2). Yes, the pedals are quite rare, the cleats belonging to these pedals are even more difficult to find. But all of this stuff is really worthless if you don’t have the proprietry Diadora Power Drive shoes.
Of course a special hole pattern for the Power Drive cleats, redundant slotted cleats, a fancy string system with a knob to tighten the shoe... Soon I will find out how it all works (or not).

Diadora Power Drive SA 210 pedals

Diadora Power Drive pedals and cleats, introduced in 1992.
Cleats are "static", meaning fixed, without float.
The other type is "dynamic".
Failed more or less, because these pedals/cleats could only be combined with proprietary Diadora Power Drive shoes. Next to that, Johan Museeuw struggled with this combination through the 1994 edition of Paris - Roubaix, where he lost the race to a stronger and more clever Andrei Tchmil. Besides that, he had problems with his full suspension Bianchi bike and Diadora cleats jammed in his pedals.
