I dont follow any specific tennis footwork, I just move naturally. I have been watching tennis pros for years so I have subconciously learned footwork patterns. ie moving in for short balls, cross steps for inside out forehand or whatever.
Is there a problem with never actually learning footwork/step patterns?
I just learned how to move better as I grew older. My body tells me the fastest way to get to the ball naturally, cross steps or sprint or whatever.
