I don't know of anything that exists like it, but perhaps someone out there will. Is there a pedal system and shoe, or simply a shoe that allows the cleat to be mounted way behind the ball of the foot so that it is nearer the arch of the foot? All winter I rode my cruiser with the ball of the foot over the pedal and found it much more comfortable for my knees and when I jumped on the road bike today I thought how much better it could be with a cleat mounted closer to the arch.
Any ideas?
