I did that for years. I was a TD and a certified PDGA official and didn't catch on that it was illegal. I did it in events and no one ever said boo to me. I moved to a new city, went to a random dubs thing and people had a heart attack screaming "FOOT FAULT!!!" at me every time I putted. It was weird and confusing, especially since no one seemed to want to explain to me what I was doing other than the scream "FOOT FAULT!!!" at me. It was a fun time. :| It was pretty easy to stop doing after I figured out the rule.Thanks for all the info. Yea i have been doing a falling putt and thinking it was legal as long as my foot stepped forward after the disc landed in the basket. Ill have to start practicing not doing that now.
