Many new road shoes that have 2 AND 3-bolt patterns do not have any kind of recessed area, so if you bolt an SPD cleat on there, it sticks out and you're walking on it just as you would an SPD-SL cleat, but you're walking on metal, not a protective rubber pad. Probably I'm just over-analyzing because I don't walk that much. I'm really focused on a stable pedaling platform, clipping in/out easily, and having good power transfer.
SH40 cleat adapters solve that problem

I use A600's which are the earlier version of the ES600. They are weighted so they always hang exactly the same way, so it's not that tricky to find the right side.
