The shoe-surface interaction carries both performance and health-based implications for soccer players. As soccer is often played on natural grass surfaces, previous mechanical tests observing shoe-surface traction have examined the interaction on natural grass and reported averaged traction coefficient values. The aim for this study was to explore spatial changes within the playing surface, as well as examine if degradation over the testing period can alter these values. Through translational testing on a custom apparatus, this study showed that the average maximum traction coefficient on the same location of the playing surface was significantly lower than results reported at different locations (2.66 vs 3.05). The influence of the initial trial, however, was highlighted. Isolating and reporting this trial, as well the average result that excluded the first trial, presented traction data that accurately reflected the maximum traction of the playing surface as well as tractional changes over the entire trial.
