This term is also applied to snowboarding
, and occasionally surfing
. Theories are that this has something to do with the relative strengths of the legs, or the overall footedness
of the rider
, i.e. right-footed or left-footed. There was originally some attempt to connect riding style with handedness
(right or left), however handedness has been demonstrated to be considerably independent of footedness.
I happen to ride regular-footed, so this node gets a longer write-up than the other one.
