The font used for the “Just Do It” slogan by Nike is called Futura Condensed Extra Black. This typeface was designed by Paul Renner and is known for its bold and clean appearance. It became popular when it was used for the Nike slogan “Just Do It”, which was created in 1988 at an agency meeting of Wieden+Kennedy.
This is a commercial type face. But you can use the OPTI Futura Extra Black Condensed Font as alternative.
