This study assessed human kinetics in relation to golf shoe outer
sole design features during the golf swing using a driver club by measuring
both within the shoe, and beneath the shoe at the natural grass interface.
Three different shoes were assessed: metal 7- spike shoe, alternative 7-spike
shoe, and a flat soled shoe. In-shoe plantar pressure data were recorded
using Footscan RS International pressure insoles and sampling at 500 Hz.
Simultaneously ground reaction force at the shoe outer sole was measured
using 2 natural grass covered Kistler force platforms and 1000 Hz data acquisition.
Video recording of the 18 right-handed golfers at 200 Hz was undertaken
while the golfer performed 5 golf shots with his own driver in each type
of shoe. Front foot (nearest to shot direction) maximum vertical force and
torque were greater than at the back foot, and there was no significant
difference related to the shoe type. Wearing the metal spike shoe when using
a driver was associated with more torque generation at the back foot (p
< 0. 05) than when the flat soled shoe was worn. Within shoe regional
pressures differed significantly with golf shoe outer sole design features
(p < 0.05). Comparison of the metal spike and alternative spike shoe
results provided indications of the quality of regional traction on the
outer sole. Potential golf shoe outer sole design features and traction
were presented in relation to phases of the golf swing movement. Application
of two kinetic measurement methods identified that moderated (adapted) muscular
control of foot and body movement may be induced by golf shoe outer sole
design features. Ground reaction force measures inform comparisons of overall
shoe functional performance, and insole pressure measurements inform comparisons
of the underfoot conditions induced by specific regions of the golf shoe
outer sole.
