    I find this design intriguing. Any have any experience with these? I have no affiliation with either FM or Dr. Grossman other than seeing Dr. Grossman lecture on his design.

    Superficial poor understanding of pathomechanics and foot orthotic design. Ignores the actual scientific evidence. Word salad.

    Dr Grossman manufacturers an orthotic he calls the Smart Sport Orthotic. Basically this orthotic entails a 3mm forefoot post to control motion produced pronation. Dr Grossman contends that many orthotics, which appear functional statically, are totally dysfunction dynamically.
    The Smart Sport Orthotic is a direct spinoff from the Postural Control Orthotic patented and sold by a company in Tacoma Washington. I am surprised that their attorneys have not notified Dr Grossman of his infringement on their patent.

    I read Dr Grossman’s comments with interest. Some of the nuisances do not make sense but sometimes I just have to see what they are talking about. In one sense, it sounds like he over pronates the patient at heel contact to achieve the centralization of heel pressure, and the pressure on the big toe. I do like that he focuses on the lateral column stability and drops the first met pressure, and does not use cut outs. He may have to use vertical medial phalanges to avoid arch pressure, instead of tradition foot orthotics (much like a UCBL) if he is valgus wedging the heel. There are good and bad aspects to every technique. Or, if I can phrase it better, only some of your patients will fit into an orthotic model to help them at that time. I use 6 techniques routinely, the Inverted Technique is one, to help my patients. I am excited to be learning the DC wedge from Dr. Smith. Some point I will have to learn where Dr. Grossman’s technique applies to my patients. Rich

    Hoping to get more discussion going .

    So in my clinical experience, the most problematical feet I see are as described here-

    Along these lines, if these feet have a laterally deviated STJ axis, could this create a functional forefoot varus?

    Does the lateral hindfoot post get the first met to a more rectus position and the lateral forefoot post then facilitate hallux dorsiflexion?

    I have a flexible cavus foot type and ordered a pair of the prefabs. They actually feel quite good and I do not feel like they pronate my foot.

    So I realize that I am a sample of 1 and my clinical experience is just that, mine alone.

    It's been a long time since I saw Dr. Grossman speak, but my memory is that he did not offer any thoughts on the mechanism of action of his design.

    I do remember though that he based his design on in shoe pressure mapping of many patients with plantar fasciitis and the mapping showed most of the PF patients demonstrated Functional Hallux Limitus. He then tried tried different orthotic design approaches and found that the lateral heel and forefoot posting with the medial flange was most effective at promoting hallux dorsiflexion.

    What say ye?
