I will try to give a couple of suggestions. Ralph first I would leave it alone unless you are having injury problems. If you are having injury problems these are methods I have seen work. We take a flat spenco Insole glue it on top of the orthotic, or arch support. We then add a piece of rubber to elevate only the #1. You can go at this by starting high and grinsding down, or start a little low and build up. Second I have seen relief by adding a small 1″x1″ piece of cork/felt to the medial corner/front of the orthotic (underneath) the height is a variable and you have to be creative. Third some Morton's Toe Runners like a low-heeled curved lasted shoe because they feel that their big toe is in ground contact. We understand that this foot type will generate varying forces up the kinetic chain. One of three things happens, better, worse, same. We can add a small amount of felt to the arch and the runner may feel it in his/her back,butt, hamstring,calf, ankle, etc. This is still a trial and error method. As I said at the start if you are unijured I would leave it alone.
Sue, what you are describing is “lateral pelvic tilt.” Some of the old school professors have claimed that this is the root cause of all the running injuries (or most of them). The short side is normally the dominant side (stronger). The high side is usually weaker (not always). We x-ray you barefooted, STANDING. We are looking for any signs of hip misalignment (dysplasa). We test strength and balance. Strength with one leg presses and one leg squat. Muscle imbalance with a squat bar to see if you do a squat does the bar tilt? We can try to strengthen the weak side and stretch the strong side. Some runners find that a small (less than 1/2 ) the shortage helps them in the transition phase.
I would strongly suggest that you have a friend videotape you running especially front and back. If we run you at a track with lane lines bisecting your body, can you hold the line, or do you wavier. If you waiver there are imbalances. It may be strength,, range of motion, flexability, or all them.
Sue, I have suggested trying on a pair of Newtons. If possible you might want to try a pair of MBT shoes to see how you feel with a different alignment.
this all makes sense…i 'know' i waiver…..would it be consistent that i actually lean into the high, nondominant side. When things are really out of whack, my arm on the dominant side crosses way over my midline and when i run next to someone. I actually share office space with a PT that videotapes gait, probably should have had her do it awhile ago.
