Bill Wallace was undefeated in Professional Karate Association's (PKA) Middleweight Division. He is well known to the Karate world simply as Superfoot, which is symbolic of his awesome left leg that was once clocked in excess of sixty miles per hour. He left a string of battered and bruised bodies along the martial arts fighting trail. As a national champion point fighter, he captured virtually every major event on the tournament circut. The more prestigious victories included: the U.S. Championships (three times), the USKA Grand Nationals (three times) and the Top Ten Nationals (two times).
