I went to a Look pedal system last winter to solve a hot feet problem I used to have on long distance rides. I combined that with purchasing a new shoe with a stiffer sole.

Unfortunately I am still having a problem. It doesn't come up until mile 60 or 70 of a long ride, sooner if I am doing a lot of hard climbing.

I have tried moving the cleats back, so that more of my foot is centered over the pedal. My feet have a fair amount of sideways movement inside my shoes, but I don't know if tightening the shoes is the answer or if leaving them even looser is.

I am interested in hearing from some of you about how you solved this problem.
