Hi,

Anyone who can pedal well without using the inside ball of the foot
is way beyond my comprehension. Outside is usually those that
pedal very badly on the instep of the foot, with wrong seat height.

I use toe clips in my road bike and plain pedals on my folder.

On the folder taking it easy I often pedal with the front of my feet.
(With a correct high saddle height it is a little more relaxed.)
i.e. stand up with with you heels of the ground, its easy. Same foot
position as running. Transfer that weight distribution to your pedals.
It is impossible to ride like that on the outside of your feet.
(It is mainly ball of foot and big toe, just like running.)
It is also good for spinning downhill.

Moving your feet forward on the pedals should reach a neutral position.
I generally ride both bikes in that position, but sometimes jam both
feet forward into the road bike toeclips for something different.

rgds, sreten.
