In table tennis, footwork is important for all levels.  Using the Newgy Robo-Pong 2050 is one of the best ways to improve footwork.  Most players try to improve their side-to-side footwork, which is important.  However, only a few players try to improve their in-and-out footwork.
 
In-and-out footwork is vitally important for the slow block, especially when you are away from the table.  Watch how Joo Se Hyuk demonstrates the stepping in on this video:

Guess or Not to Guess?
 
     In table tennis, there are 2 aspects of anticipation.  The first is to have a reasonable guess as to where your opponent will hit the next ball.  The next aspect is watching his body position and racket angle and adjusting based on the direction of his swing.

Four Elements of Footwork
 
“If I can lose 10 pounds, my footwork will really improve!”
This is a common statement made by hundreds of club players nationwide.  Yes, their footwork probably will improve, but losing 10 pounds is only 1 of the 4 elements to having excellent footwork.  I have seen some great athletes (in other sports) who had very poor footwork in table tennis.  I have also seen some 300 pound table tennis players who had decent footwork.
