Walking feet are not designed to be used while sewing backwards. The walking foot has only one direction, forward. The up and down motion of the needle moves the walking foot and it has no way to determine the direction you are sewing. Therefore, it always moves forward even if the lower feed dogs are going in reverse. Continual use, while sewing in reverse, will eventually break your walking foot.
I didn't know this-must have missed the thread discussing it-I usually use my walking foot mostly for binding, but have a few times used it for SID. I have not had any problems taking a couple stitches back with my foot, but as I said, I don't use it much except putting on binding. I'll keep this in mind-I continually learn someting new on this site!!
