Thats not as bad as what i had in my mind, of doing a really high kick to the skull and the only thing makign contact being your toe, for that you might as well ahve just front kicked them in the knee or something. and this has just made me rememebr some people have you instep kick with your toes as opposed to shin or top of your foot. barefootedat that. As for the footware comment @jobo TKD is barefooted, thats pretty much the norm and rule, they make little consideration to the dynamics of kicking with shoes on and which types. You cant pull off many of their fancy kicks in boots anyway. My side kick is using the edge of my foot because i have done it in shoes more than i have barefooted and thats how my shoe sort of forced my foot to go. which on reflection just now may be one of the reasons some styles do it that way as norm. Not nessisarily, if somone breaks into your house you are probbly shoeless or maybe have slippers. Its militantly cultrual that way in some places like japan. But as for how most people live, shoes tend to come off when they get home unless they plan on going out again shortly.
