Definition: A walking foot has built-in feed dogs that grip and advance the upper layer of fabric that's traveling through the sewing machine in unison with the machine's feed dogs, which grip the underside of the fabric. The action of this special sewing machine foot helps keep the layers from shifting apart as they move through the sewing machine.
A walking foot is essential for pucker-free, straight line machine quilting. It is a handy tool to have when you sew together the multi-layers of a rag quilt and when you work with heavy fabrics such as denim.
Also Known As: even feed foot
