Footwork is everything your feet do between shots: the small split step as your opponent swings, the sideways shuffle along the kitchen line, the two quick steps that get you from the baseline to the net, and moving with your partner like you're connected by a rope. It isn't a shot — it's the reason the shots work. Balls you reach balanced are easy; balls you reach leaning are donations.
When you use it
Constantly. Every shot you hit starts with whether your feet got you there in time to be still. The kitchen line is where it matters most: rallies there are won by players who shuffle two feet sideways and hit from a set stance, and lost by players who lunge, cross their feet, and swing while falling.
What it looks like at each level
At 2.5, feet are flat and planted; players reach for balls and wonder why they pop up.
At 3.0, the split step shows up sometimes, and players get to the line — just not always together.
At 3.5, players arrive at the ball set and balanced; the paddle does the work because the feet already did.
At 4.0 and up, anticipation joins in: players read the rally a step early, hold the line under fire, and move as a pair without a word.
The mistake almost everyone makes
Running through the shot — still moving when the paddle meets the ball, so the swing has to fix what the feet broke. Good footwork actually looks slower: arrive early, stop, hit. If your 'bad shot' keeps happening at the same moment — stretched wide, caught mid-court, leaning back — it was never the shot. It was the feet.
