I found this to be a problem as well...so I looked and felt how my foot was pressing the pedal. You push your toes down which puts constant stress on your ankle and tendon in your lower leg. I turned my pedal around where the higher end of the pedal was at the front of my foot. Yeah!, I had a lot less strain on my ankle and lower leg...barely had to touch the pedal with now the top of the pedal at the front of my foot. Try this and note how your foot is now not having to press so far down and your lower leg is not being used as much either. Different feel, but works for me.
