Update and request for advice.

My ride home is longer than my ride to work. By the time I got home, I was experiencing, of all things, some tenderness in the ball of my left foot like a blister trying to form. I have been wearing these shoes for weeks now with no problem. When I got home, it occurred to me that perhaps the firm Brooks saddle, compared to my padded saddle, had effectively increased my saddle height, causing me to rock slightly and perhaps reach a little with my foot, causing some excess movement where there was none before. As I thought back on it, the saddle seemed to be squeaking more than I thought it should and I wondered at the time if my pedal stroke was less smooth for some reason. I dropped my saddle by about 1cm and we'll see how it goes tomorrow. Does this sound reasonable?
Thanks,
Raymond
