Perhaps you’ve misunderstood Neallyman? They have more than enough grip for me, but they have less grip than my MG1s (whether in my AM40s or my 5 10s, or in any other shoe). So someone who wants ridiculous amounts of grip wouldn’t be happy with them, but everyone else would.
Too much grip’s just annoying, I’ve taken pins out of the MG1s but the Nanos don’t need that as they’re not that grippy in the first place.
Sticky shoes- whether it’s Vans, Shimanos, 5 10s, whatever- all provide enough grip on pretty much any pedal, but some people like the confidence boost of too much grip, and others need it to make up for bad footwork.
