Football shoes with plastic nails on the soles are not good either. They can easily slip on wooden boards or concrete floors.
It is recommended to wear light Xintian diameter shoes and tennis shoes (rubber shoes are also acceptable), and the heels and soles have patterns.
The perfect score of 2.4 meters is not high. As long as you use the right method, it is not difficult to get the perfect score.
Let me give you some advice:
There should be explosive force when taking off (fast take-off), and the swing arm should be combined when taking off; Take-off should have a certain height; The abdomen swells in the air; When landing, tuck in your abdomen, lift your legs and follow your upper body quickly (avoid sitting back). You can experience it when you practice. When you land, your heel will land first.
Give you a picture for your reference.
