| Abstract: | Abstract The purpose of this study was to determine the relationship between use of the conventional football shoe and the epidemic of knee injuries occurring in organized football. All knee injuries in the Public High School League in 1968 and in the Catholic High School League in 1969, when players in the respective leagues wore the conventional shoe, were documented. During the 1969 and 1970 seasons, all Public League players wore “soccer type” shoes with molded soles containing fourteen ?-inch cleats. All Catholic League players wore similar shoes in 1970. In both leagues, all practices and games were conducted on natural turf. Injuries occurring with the soccer type shoe were documented. Comparison of the two groups demonstrated a marked decrease in both the incidence and severity of knee injuries in both leagues when the players wore the multi-cleated shoe. It is strongly recommended that the conventional football shoe be condemned and that only shoes meeting the following specifications be permitted: (a) synthetic molded sole, (b) minimum of 14 cleats per shoe, (c) minimum cleat tip diameter of ½ inch, (d) maximum cleat length of ? inch. |
