In a flèche, a fencer transfers their weight onto their front foot and starts to extend the arm.
The rear leg initiates the attack, but the ball of the leading foot provides the explosive impulse that is needed to drive the fencer toward the opponent.
After attempting the hit, the fencer continues to move forward, running past their opponent, to avoid the riposte if he or she was parried, or a counterattack.
Infraction of the rule may result in a warning, awarding a touch to the opponent, and/or expulsion from the competition.
[2] In épée, contact merely results in a stopping of play without penalty, unless it was done with jostling, brutality, or to avoid being hit.
