Welcome to these forums. You've heard right -- footwork is of paramount importance and Roger Federer incorporates some of the best, most efficient footwork in the modern game. Good footwork should contain the following elements:
- Ready Position
-
Split-step
- the Step Out
- movement to the ball
- optimal hitting stances
- recovery steps (to an optimal position)
The Ready Position can also include swaying and "ready steps" prior to the split-step. The
split-step is a timing hop that is initiated on the forward (or upward) swing of your opponent's racket. If you time the hop properly, you should be landing just as the ball has left your opponent's racket. This hop should sync you up to your opponent's shot and allow you to move more quickly in any direction immediately after landing.
The first step after the split step is usually taken with the foot closest to the direction that you will need to move to intercept the incoming ball. This step, know as the
Step Out, should be part of your unit. Movement to the ball will usually involve large walking or running (sprint) steps toward the ball and smaller adjustment steps as you get closer to an optimal hitting position.
Optimal hitting stances will allow quicker, more efficient recovery times. This will include neutral, semi-open and open stances. Closed stances should not be the norm for FHs and 2-handed BHs. However, they are fine for 1-handed BHs.
The basic recovery step is a side shuffle. If you need to recover from a very wide shot, you might incorporate a couple of sprint steps followed by the side steps (shuffle). This side shuffle should allow your to recover toward some optimal position and should also allow you to incorporate another split-step and your opponent is about to make contact with the ball.
The optimal recovery position will usually not be the middle of the baseline unless your own shot is moving toward the middle of your opponent's court. If you hit a cross-court shot, you should not recover all the way to the middle. Take a look at this video to see what I mean:
