Well, the point is if you place your arch firmly on the pedal the way
kids everywhere ride bikes with rubber pedals & no retention (i.e.,
using the edge of your shoe's heel to keep the foot located) you are
going to be loading your arch right square in the middle, under the
keystone in your illustration.

Arches support the load by distributing the forces to the ends of the
arch, not the middle. I suspect feet (which are a natural arch
structure) operate on the same principle. In the case of the foot, the
two "ends" are the heel and the ball of the foot.

In the same vein, this is why saddles like the Brooks B17 support the
weight of your body on the natural arches in your pelvis, not on a
more sensitive area between them ...

and who walks loading their arch? Sometimes it's hard to tell April

We all learned to position our foot over the pedal like this:

Your flat-pedal vendor wants us to move that big toe knuckle all the
way forward to the leading edge of our huge flat platform pedals. I
might be into that foot-pedal positioning if I was riding a beach
cruiser at Burning Man:

But for normal riding? I think that's a little too radical for my
tastes. Just because I use my heel when I walk does not necessarily
mean I must load my heel when pedaling a bicycle.

There was something I always liked about Grip Kings (MKS
Lambda). Though narrow (good for clearance), too thick, and not
quite grippy, at almost 120mm long, they center very nicely
under your arch and give you support mostly from ball to heel -
maybe not quite with my ice skate feet. But they gives you
great mash, great spin, and low strain on your arches with any
shoes.
Deac notwithstanding, if you're pedaling on the ball of your
foot, you really need to be in shoes with solid shanks,
otherwise part of your pedaling energy goes into straining (and
injuring) your arches.
Most grippy flat pedals are wide and short - some too wide
endangering clearance, and most too short. some are over 110mm
wide now, but most are merely 95mm long.
Lived a year on my Race Face Atlas now. I bought these because
they were "oversquare". 101mm wide x 114mm long (and a near
freakish 12mm thick). . Aside from a too early (warranty) axle
click, I've really loved these pedals. With the way they're
holding up now on the new axle, I'll also have to say they're
worth the price.
Pedaling Innovations in CO has been making The really long pedal
now for about a year, the Catalyst. These are 95mm wide x 128mm
long - this is a serious platform, and the narrow width (by
current standards) keeps cornering clearance reasonably safe.
They have a pretty good argument on their home page why long is
better, and they're getting pretty good reviews (though they are
heavy). Note Deac, loading the ball of your foot is for running
and jumping - you need the full arch - ball to heel - for
lifting weights and mashing.
