^aAdjusted for sex, age and body mass index.

^bParent-reported Oxford Ankle Foot Questionnaire for Children (OxAFQ-C) domain scores were based on n = 49 due to missing data.

^cLinear regression analyses performed for footwear fit were based on n = 48 due to missing data.

^dIll-fitting: representing the greatest disparity between the participant’s foot and footwear length and width dimensions; expressed as a percentage. The values that defined the lower median (ill-fitting) were as follows: length (shoe 14.3% shorter to 10.8% longer than foot), width (shoe 26.5% to 4.9% narrower than foot).
