I suffered with a hot foot (mostly my right) all last bike season and this winter while I'm on the trainer. I have been riding with Sidi MTB shoes and spd cleats. I've just ordered a new pair of SIDI Genius 5 road shoes (1/2 size larger) hoping this will help the problem and am wanting to change pedals as well. I'm considering Speedplay Light Actions. I know many of you have the same problem. Has anyone found anything that helps?
