Kelly- I have Look style pedals which have a larger platform. I also have moveable cleats. In addition, I wear wool socks (smart wool) which keep my feet cool and dry in very hot weather. Look in this part of the forum for hot feet, etc. for more suggestions

Since your sit bones seem better, you might try raising your stem just a tad to see if that helps.

Make small adjustments- that's the key to finding the right fit.

Good luck!
