I realized this week that my two daughters were snowboarding the wrong side (5yo and 4yo), they were playing on their online scooter, and I realized the one I tought was goofy, was pushing with the left foot, and the one I thought was regular was pushing with the right foot...
I tried, and as I am goofy, I was clearly pushing with my left foot (back on the snowboard).. just sharing as an idea to test...
