I have an old Kenmore, I think made in the sixties, I only have one foot for it, does straight, zig-zag, and I think maybe 2 other stitches, have no idea what the foot is called, LOL! My newer machine came with all kinds of feet, I've tried different ones, and I just use the one I like depending on what I'm sewing. Of course have to use correct one for the decorative stitching and such. I had never even heard of a walking foot!
