With over 50 intrinsic additions, everything is cutomised to fit onto the device at what ever height, shape or density that you require. In the prescription form, you can add specific notes. Unlike any other lab, we do not charge any additional fee for any modifications that are added. Below please find just some of the intrinsic modifications to the shell such as intrinsic heel raises (long or short), flares, flanges, widths and also some of the 50 intrinsic "pads".
