Instructions
Break into your run, making sure there isn't a defender within 10 yards of you. High stepping slows you down; if a defender is close, high stepping could allow them to catch you.
Hold the "Circle" button as you get inside the 20-yard line, if you're playing Madden on the PS2 or PS3. The high step taunt does not work unless you are inside the 20-yard line.
Press and hold "B" when inside the 20-yard line, if you're playing Madden on the XBox 360.
