Foot fencing is where athletes keep one leg in the air and hop on the other foot in an attempt to score a kick with the lofted leg.

It is technically legal but considered bad form.

The style became increasingly common after the adoption of electronic hogus as the sensors could detect a slight poke of the leg and register it as a hit, while a human judge would likely not score the hit due to a clear lack of power. 

Some tournaments now impose rules about how long one leg may be lofted in the air at a single time, usually limiting it to around three seconds.

WT appointed seven people to the Competition Rules Improvement Committee following reports from referees and competitors to improve the competition rules so that taekwondo can become a more enjoyable sport to watch and participate in.

Olympic silver and bronze medallist Lee Dae-hoon and double Olympic champion Hwang Gyeong-seon, both of South Korea, are included in the Committee, which will be in office until December 31.

They plan to examine the rules and scoring methods as a priority.

The Committee's proposed plan is set to be applied incrementally, beginning at the 2022 World Taekwondo Championships in Wuxi in China.

Meanwhile, WT has announced it plans to supplement the electronic protective gear system introduced from the 2009 World Championships and the 2012 Olympic Games to enable judges to make fair decisions.
