What is the historical reason Karate and Taekwondo recommend kicking with foot instead of shins for Round kicks (different from Muay Thai)?
In Krav Maga, they teach to kick with foot, since most of the Israeli soldiers are wearing sturdy thick army boots, and the small bones will not break, while giving longer kicking range. Is there a reason, Karate and TKD recommend this? Maybe warriors wear metal samarai boots during ancient times?
I see many young adults especially in TKD learning, and last thing people want are kids having injury in self defense.
Note: Prefer post not be about which martial art is better, and more professional about understanding the historical context.
