    Hi,
    I have been sending my foam impression boxes to various orthotic manufacturers over the years for my prescription orthotics. I make my own simple orthotics (have little desk top grinding machine) but don't want the hassle of creating the positive plaster casts. I also sometimes use library type orthotic system which is computer generated and cnc milled. I always find that no matter what orthotic company I use, the orthotics are quite expensive and I end up making many modification to it myself before I have what I want. I have been looking at heat mouldable orthotics recently as I am happy to add eva fillers, heel posts, and forefoot extensions myself and wondered if these heat mouldable systems would capture the orthotic shell. From what I can see, most of these heat mouldable systems seem to be an Eva type material but I would prefer a carbonfibre/polypropylene shell to which I can then add eva filler if necessary. Can anyone tell me if there is a heat mouldable carbonfibre/ polypropylene sytem out there which can be moulded to the patients foot or into the foam box impression? - and if it is any good. Many thanks.

    Issy

    Going out on a limb here, because materials is not something I'm expert in, but I would say not.

    Neither of the materials you mention deform or become elastic at the relatively low temps you would need to mould directly to the foot, or to a foam box.

    Northwest Podiatric Lab in Blaine, WA ( http://www.nwpodiatric.com/ ) has a line of excellent carbon fiber pre-fabs known as "Pre-Custom." They use a proprietary carbon graphite fiberglass blend, DBX6, which is remarkably strong yet about 1.5 mm thick. I mold them with a heat gun.

    Such devices are not a substitute for a custom made prescription orthotic but are usefull as one needs something superior to a standard pre-fab device. I also utilize them as orthotics for dress shoes. If a patient already has a custom device and positive casts, one may mold the devices to that cast.

    I doubt that there is a product that could be heat molded in a foam box considering the effect that heat would have on the foam. It is relatively easy to pour plaster into the foam box to create an uncorrected positive cast.

  5. I got a pair of these that they made for me at a PFOLA meeting some years ago. They're not bad. Not sure what the exact material is, but they look and perform similar to a polyprop. device.

    +1 for the DBX6 product from northwest podiatric, if you need their UK contact details message me and i will dig them out

    the product is moulded either with a heat gun or an oven, normally it is pulled over a positive but i wonder if it could be moulded direct to the foot with a stockinette over the foot to protect form the heat, again i can find out if this works form my contact at their labs in the US

    Steven,

    Not sure where you're from but do you know if JMOrthotics have a U.k. Rep. or can you only buy directly from U.S?

    Thanks Issy

    Hi issy.

    These polypro prefabs are heat moldable and easily modified.

    They are relatively inexpensive too.

    U.S based, so maybe consider a bulk order to make it feasible.

    Cheers
