What primarily fixed my situation was to change to +4mm pedal axels and adding a 1mm washer to each pedal, for a total extension of +5mm on each pedal.

Other changes I made to help left leg/foot pain/numbness were moving the cleats all the way back (foot forward on the pedal) and shimming my left cleat by 2 degrees. All these changes came from my Specialized Retul fit in Boulder in January. I use Shimano yellow cleats that are centered as to float.

I think the primary benefit was changing to the +5mm pedals (including the 1mm washer). In other words, an increased Q factor. Abnormal hip pain is now gone.
