Today i did my first long hilly ride using clipless pedals. I was ok for the first 3 hours but after that i experienced pain in my toes (both feet) which was quite severe. I had to get off the bike and remove my shoes to stop the pain. Any ideas what may be causing this and how i can stop this happening again?
The shoes are Shimano mtb shoes in the same size as my flat Shimano shoes so i think i have the right size.
