This study examines the relationship between floating toes and plantar arch among 416 preschool children (boys: 208; girls: 208; age range: 4–6 years). Contact surface area of the feet in each participant was pictured 5 times while they were standing barefoot on a pedoscope. Untouched toes are the toes that did not show up in more than 4 of the 5 recorded pictures. Plantar arch ratio was used to evaluate the size of the plantar arch. No significant differences were observed in the plantar arch ratio between the children with floating toe and those without floating toe. Furthermore, no difference was observed in the number of floating toes (0 floating toe, 1 floating toe, >2 floating toes). The correlation coefficient between the number of floating toes and plantar arch ratio was not found to be significant. Therefore, this study clarifies the lack of relationship between the floating toes and plantar arch among preschool children.
