Why does my right Achilles hurt when I use my Sidi S Pros My right Achilles has been hurting when I ride with my $300 Sidi S Pros, which I bought a few months ago. I don't want to waste my money by not wearing them when I ride. How can I fix my pain in my right Achilles ?????? 
Please help if you can.
Thanks
I've had some bad pain in my Achilles before. For me, it was a problem when I did a long ride with my seat too high and using SPD shoes and pedals. Because of the seat height, I was bending and flexing my ankles to push the pedals slightly at the bottom of each pedal stroke, this is called ankling. If you find yourself doing this, creep your seat down slightly and watch your pedaling form to see if that removes the need to apply force with your ankles during the pedal stroke.
