A word of caution, I bought a generic walking foot with a metal "claw" to use with an older machine. I quit using it when I discovered the metal claw was wearing a groove in the needle bar on my machine. It could be that the generic foot did not fit quite right, and even though it functioned just fine, the metal claw rubbed against the metal bar in a way it shouldn't have. The one with the plastic claw does not do this. Just something to watch out for.
