Custom AK socket shapes are created with a 3D solid modeling software using splines to define smooth contours and transitions. A digital model of your best performing brim and overall socket shape can be created for use in new test sockets. A custom digital model allows you to capture the details of a brim and socket shape after the trimming and heat flaring process from a diagnostic fitting. You could choose to start with our primary shape for an initial fitting or work from an existing socket to create a custom model. Your custom shape can also be refined over time with fitting feedback. Our online order forms allow for easy ordering of new AK test sockets. A demo AK test socket order form is available for review from the main menu Order Forms -> Demo Online Order Form.
