you could check 'Nancy's Notions' on line- they carry a number of different feet...Clotilde's does too.
personally i would not spend money on an 'off brand' foot for my viking- it was way too expensive to mess up using the incorrect feet.
the one you purchased at joannes was probably a long shaft foot- you need a short shaft foot. they are called- hopping foot, darning foot and quilting foot- depending on where you shop for it- it should move up & down (hop) with each stitch
