My random contribution is: put a layer of Saran Wrap between the pad of your shoes and the clips. I have odor eaters in my shoes and put Saran Wrap under them and it made a huge difference. The freezing metal of my clipless pedals made it impossible for me to ride for more than 30-40 minutes in winter! I also put a layer over the mesh on the toes... It made all the difference. Gotta love the Wrap!
