Newer Shimano R7000 pedals having smaller contact area than older R5800? I was comparing Shimano PD-5800 and the newer PR-7000 SPD-SL pedals. Judging from the metal contact plate on them, the newer model seems to have a far smaller contact surface area.

Is this correct judgment or are the metal plates only part of contact area?

The metal plates are only part of the contact area. In my opinion the 5700 pedals are SO good, you can’t go wrong with either model.   If cost is a factor you will get years of excellent performance and durability from both.

There is a smaller rectangular raised section between the metal contact plates that also contacts the cleats.
