Backside Front Flip Again, this "Backside" Front Flip is pretty funny. First of all, heelside is a direction you cut and backside is a direction you spin. Most likely, the reason they called it a backside front flip was because no one had spun a different direction yet, and they only had frontside spins. Either way, this is a taste of Shapiro's complete domination of the sport in those days. Not only did he win the majority of the contest, he invented quite a few of the tricks we do today.
