title: Collar height and heel counter-stiffness for ankle stability and athletic performance in basketball.
abstract: This study examined the effects of collar height and heel counter-stiffness of basketball shoes on ankle stability during sidestep cutting and athletic performance. 15 university basketball players wore customized shoes with different collar heights (high and low) and heel counter-stiffness (regular, stiffer and stiffest) for this study. Ankle stability was evaluated in sidestep cutting while athletic performance evaluated in jumping and agility tasks. All variables were analysed using two-way repeated ANOVA. Results showed shorter time to peak ankle inversion for both high collar and stiff heel counter conditions (P < 0.05), while smaller initial ankle inversion angle, peak inversion velocity and total range of inversion for wearing high collar shoes (P < 0.05). No shoe differences were found for performance variables. These findings imply that the collar height might play a larger role in lateral stability than heel counter-stiffness, while both collar height and counter-stiffness have no effect on athletic performance.
