IDT is Pfaff's name for the integrated dual feed. It's like a built in walking foot that is always there. It is part of the main shank and you can attach all the different feet as needed. It can be disengaged if you don't want it and when using the embroidery unit it disengages too. The dealer says that with this feature you can perfectly match stripes or patterns and there will be no slippage of the fabric layers. Hope that explains it.
