Q: Should i kick with my instep?
A: Short answer, No! (unless of course, you want to break your foot!)
Honestly, all sarcasm aside, the only benefit I can think of is the greater distance covered when hitting with the instep with a kick like a roundhouse. Its just not worth it in my opinion.Here’s why: Your foot and ankle have 26 bones, 33 joints, and more then 100 muscles, tendons and ligaments.
Try this little exercise: Make a fist, and knock on the top of your foot like if your knocking on a door. You’ll notice how fragile that area is.
Your better off hitting with the shin, the ball of your foot or heel. (depending on the kick of course).
Now whether your kicking with shoes or barefoot is another can of worms because in savate, they kick with the point of the foot. (they wear shoes) and its incredibly effective. If it’s a street fight, this is incredibly effective.The bottom line: Avoid kicking with the instep, with other options available, its just not worth it.
