Do not buy feet from EBay , Amazon, or any other online seller, including Bernina. I have 3 sets of walking feet, bought, you guessed it, including Bernina. None fit or work properly on my Old Style Bernina. Finally did an online search for the nearest Bernina dealer, for me a 45 minute drive. Took the machine with me and they let me try the feet, and I bought them. A little expensive, but in long run it will be worth it Find your nearest Bernina dealer, if the drive is to far, call them, maybe they have just what you need.
