Im a footslogger myself. I certainly USE cavalry, but never as the main composition of my army.
Typically I'll wait for the enemy to come to me, using my archers to shoot them up along the way, then pin with spears/high defence infantry while my shock troops/cavy flank. I generally have some light cavalry around to mop up as well.
The only exception is my all cavy-archer armies, typically for use with the Muslim factions or Russia.
