It is common to have full length covers on ski orthotics. Traditionally, a fairly rigid cover will cover the orthosis and extend all the way to the toes. When using the cover for ski orthotic it must be rigid in order to allow the device to easily slide into the boot. Soft covers tend to fold up underneath the orthotic as you are putting it into a boot.
This is how I have traditionally made orthosis for skiing. However, over the past couple of seasons, I have started making devices without covers. I find that it is much easier for the patients to put the orthosis into ski boots when there is no cover on the device.
The cover really does not play any sort of stabilizing or mechanical role. It is very traditional to have a stiff full length cover but the bottom of the boot is completely rigid anyway and the rigidity of the top cover does not add anything to the control of the device.
ProLab takes a scientific approach with our orthoses by integrating evidence-based medicine into orthotic therapy. Our team of Medical Consultants regularly evaluates the medical literature pertaining to orthotic therapy and biomechanics. ProLab clients are encouraged to contact a medical consultant whenever they have questions about an orthotic prescription.
