Edit this basic teaching
Of course, there must be sufficient preparation before sliding, and the flat bottom and soft bottom are suitable for sliding.
Step 1:
Find a pair of tight flat shoes. You can use soft-soled shoes at first.
Step two:
Make sure that the floor you practice is not too rough, and try to find a smooth floor.
Step 3:
Stand with your feet together, with your left foot slightly in front of your right foot (the front end of your right toe should be in the same line as the middle of your left toe).
Step 4:
Then lift the heel of your right foot to make it look like you are walking. Stand in front of your right foot and keep your left foot in place (be careful not to move).
Step five:
When you put down your right heel, move all your weight to your right foot and slowly drag your left foot backwards so that your left toe is flush with your right heel. When doing this step, the left heel should be slightly off the ground, and the left foot should not step down, otherwise it will not slide. Make sure to slowly lower your right heel while moving your left foot. Controlling speed requires more practice.
Step 6:
Keep practicing the above steps until you are sure that you can move without obstacles.
Step 7:
Once you can master the above movements, put your left foot forward, but don't touch the floor. Make it look like you just kicked it on the ground. Move one foot from the front of the right toe. Don't lift your left foot anywhere.
Step 8:
Move your left foot back to its original position and lift your right heel again. Bend your left leg and repeat step 5. Keep practicing until you understand all the essentials, and you can do whatever you want and get approval from others. Finally, you can overcome gravity, so that you can walk in space like a professional.
Step 9:
Once you can master the bending of your right foot, exchange your feet, try to do the same with your left foot, lift your left heel, put down your left foot and slide it backwards with your right foot, support it with your left foot, extend your right foot, then lift your left heel, then slowly move your right foot backwards and put it down again.
