I have been a sports podiatrist for 47 years, and retired several years ago. I was Board Certified in Podiatric Orthopedics and Podiatric Surgery. I was also a Fellow of the American Academy of Podiatric Sports Medicine. I am also a Licensed Massage Therapist (to expand my scope). I also have taken 500 hours of Applied Kinesiology starting 30 years. I am going back to practice on a limited basis as a Chiropractor friend told me that he has many patients that can't find relief. The reason I am posting this is I had a patient that went to the Good Feet Store and was charged $1500 and couldn't wear them and was unable to obtain a refund. I came here looking to see if that was true.
To make a proper foot orthosis, you have to look at intrinsic and extrinsic pronatory factors. The intrinsic pronatory factors are frontal plane imbalances and Functional Hallux Limitis.
The extrinsic pronatory factors are Equinus (tight calf muscles) and leg lengths (99% of the time they are functional caused by either Ascending or Descending dysfunctions.
The 4 theories on making orthoses are the Weak Foot Theory (by Royal Whitman MD), the Balance Theory (by Carl Bergman DPM), Root's Frontal Plane Theory (by Mert Root DPM) and the Sagittal Plane Theory (by Howard Danenberg DPM).
The theory that I have been working on the last 25 years is Biotensegrity which includes fascial work and the acupuncture system which allow me to eliminate the extrinsic pronatory factors. The Forefoot Varus is an inhibited Adductor Hallucis oblique head and Functional Hallux limitis is usually caused by an inhibited transverse head of the Adductor Hallucis muscle. Using this theory, I am able to treat dancers including the one that taught the master class in Cleveland and returned her to performing.
I have had thousands of running patients over the years which includes Olympic caliber and professional athletes from the three major sports.
That being said, I am still learning on every patient I treat.
To think an off the shelf arch support is the best you can get is ludicrous. BTW, my patient that went to the Good Feet Store is currently doing well. The main problem was the previous fusion of the First Metatarsal Phalangeal Joint (the big toe joint) that required a shoe modification to allow her to roll off the front of her foot and a real pair of orthoses to help the opposite foot's Functional Hallux Limitis to stay corrected.
One more thing, I make my orthoses and I charge way less than the Good Feet Store.
