The France forward scored eight times, one more than Lionel Messi, who collected the Silver Boot. Olivier Giroud‘s four goals seized him the Bronze Boot.
Mbappe scored three goals in the group stage and five in the knockout phase, including a hat-trick in the final, which France ultimately lost on penalties.
He became only the second player to score more than six goals since 1974.
Ronaldo, to whom Mbappe has been consistently juxtaposed, netted eight for Brazil in 2002.
