I just upgraded to the Shimano PD-6700 Ultegra pedal. I'm still using my same Specialized shoes from an earlier set-up which gave me no problems. The Ultegras feel great in terms of transfer of power, but after a couple of hours in the saddle, I was feeling soreness in my feet. Do I need to loosen the cleats to allow some float or just try shifting them around to new positions until they feel right? Has anyone had these problems with these or other pedals? How did you deal with it? Thanks!
You stack height may have also changed if you weren't using Shimano pedals and SPD cleats before. The Shimano yellow cleats have 6 degrees of float. Check out some of the cycling related foot pain troubleshooting info that is online.
Thanks everyone for the replies and pointers.
I did indeed change the cleets and they are much higher than what I had before. Wondering how to compensate for that.
Pain is on the outside of each foot and a bit in the outer ankles.
If your stack height is bigger/taller then you are sitting lower; knees bent more at the top and bottom of the pedal stroke. So raising your seat by the differences in stack height may help. As you raise the seat the nose gets farther away from the handle bars so having some before and after measurements (seat height and seat nose to stem for example) can help you fine tune things.
