Abstract
The Volumental 3D scanner aims to improve traditional measurement methods by providing a 3D model with six different foot measures. Foot measures using the scanner have been collected to analyze the variability in foot dimensions among a North American sample (Jurca, 2019) as well as how shoe sizes differ from brand to brand (Jurca, 2021). PURPOSE: To explore the Volumental 3D scanner as a reliable tool for health professionals and athletes. METHODS: Twenty participants (age=33.25 ±14.0 yrs, height=169.0 ± 7.5 cm, weight=76.9 ±13.9 kg) were recruited by word of mouth. Participants removed their shoes (socks were not removed) and stood on the platform of the Volumental scanner. Once the scan was completed, participants then jogged for 30 minutes up and down a preplanned route. When they returned, they had their feet scanned a second time. A 2x4 repeated measures ANOVAs was run for each variable. In case of significance, the Bonferroni technique was applied to control for pairwise error. Intraclass reliability was assessed with the Cronbach’s Alpha (two-way effects mixed model). Alpha was set at .05 for all tests. RESULTS: Statistical analysis revealed that differences between trial and left and right foot for Ball width (F(7, 13)=2.46, p=0.076), Length (F(7, 13)=1.13, p=0.398), Girth (F(7, 13)=2.40, p=0.081), Instep (F(7, 13)=1.40, p=0.284), and Instep Girth (F(7, 13)=1.40, p=0.284) were not statistically significant. Analysis of Heel Width revealed a significant difference in the left and right foot, (F(7, 13)=37.6, p=0.001) with the left heel being more narrow than the right between each trial (p<0.001). Reliability was excellent (above .90, p<.001) for each measure. CONCLUSION: These findings suggest that the Volumental 3D scanner provides consistent measurements across multiple scans, supporting its utility for athletes, footwear brands, and health professionals.
