Help Identify Please - TKD Asian Games 2010 - What kind of footgear?

[Rumy73]

Hello Everyone,

I was watching a clip from the 2010 Asian games and noticed the players wearing some kind of new footgear (new to me atleast). Can anyone ID it? Is it legit for TKD matches here in the USA?

It looks like they are using the LaJust Electronic Impact Detection and Scoring System (EIDSS). The "socks" register a point upon impact with the Hogu. USAT is using the same system.
