There isn't a great walking foot available for the 301. The width of the available feed dogs are ALL too large. So, none will work as walking feet should with matching upper feed dogs to the lower...you can find walking feet that will fit. They need to say they've been dremmeled out and tested. Sew Classics sells them and she tests them for fit. HOWEVER, know that even though they "fit" they don't work as walking feet are designed too...there are simply no walking feet on the market with narrow feed dogs. I wish someone would wise up and back engineer a correct walking foot for the 301.
