Purpose: The study set out to investigate two different golf shoe outer sole configurations in two independent stages: A comfort questionnaire and an indoor laboratory test. Methods: Fifteen recreational and elite players volunteered to participate as subject’s. For stage l, the questionnaire group, consisting of subjects being both recreational and elite players (age: 27.7 ± 11.3 years; handicap: 7,6 ± 10,7). Subjects were approached on the local golf driving range and tested each pair of ECCO golf shoes before completing the comfort questionnaire. For stage l, each answer and perception of the two different shoes were measured. For stage ll, the indoor laboratory test, consisting of subjects being only elite players (hcp:<4; age: 23.75 ± 0.5 years; height: 1.85 ± 0.05 m; body weight: 86.3 ± 5.3 kg). Subjects tested each pair of ECCO golf shoes and completed twenty shots on artificial grass mats in the laboratory setting. Stage ll, considered the independent variables shoe (2: Soft spike model and hybrid model design); club (2: 3-wood and 5-iron) in relation to the dependent variables, ground reaction forces (Fy Max) in front and back foot and club head speed and ball speed. A two-way ANOVA was used to compare the independent and dependent variables at a 5% significance level. Results: For stage l, the results indicated that the recreational golfers (hcp>4) tend to choose the hybrid shoe model, while elites (hcp<4) tend to choose the soft spike model. Between the subjects participating in the study ~73% would choose the hybrid model compared to ~27% choosing the soft spike model after trying each pair of ECCO shoes. For stage ll, no significant difference (p>0.05) exists in ground reaction force (Fy Max) between the two variables; club and shoe selection. However, a significant difference exists (p<0.05) in simple main effects maximum and minimum (peak) force generation for the back foot within club selection (iron and 3-wood) and within shoes (soft spike and hybrid) used in the study. No significant differences (p>0.05) exist in club head speed and ball speed between any of the variables. Conclusion: The results indicate that the hybrid model seems to be the general favorite amongst subjects in the comfort questionnaire. The tendency seems to be towards the general population of golfers, while elites/ professionals prefer the soft spike model. Also, no differences were found in ground reaction forces and club head or ball speed suggesting that the hybrid model could potentially deliver similar traction as the soft spike model and thus not affecting the golf swing or outcome.
