News to me. I always install mine at the ball of the foot on all my bikes, whether it is my touring, road or mtb.
"At the front" or "at the arch", based on the amount of forward and backward movement available on the shoe (well...the ones I have), seems to be little difference, than the description implies.
Whether mine are "directly over the ball" or "at the arch" is hard to discern a difference....maybe 1/4 of the available distance from the front...so what would that be then..."directly at the ball"?
