Relationship of the Use of Short Footwear with the Development of Hallux Valgus in a Sample of Andalusian Schoolchildren

Background: Several studies have shown the relationship between poor footwear fit and the risk of feet deformities. The available evidence seems to show that the development of hallux valgus deformity in the feet of schoolchildren may be related to the use of shoes that are poorly fitting in length....

The available evidence seems to show that the development of hallux valgus deformity in the feet of schoolchildren may be related to the use of shoes that are poorly fitting in length. The objective of this cross-sectional study was to analyze the relationship between poor footwear fit in length and risk of developing hallux valgus. Methods: Using an instrument that was designed and calibrated for this purpose, maximum foot length was obtained and compared to the inner length of the shoe in 187 schoolchildren. Hallux valgus angle (HVA) was measured on weight-bearing podogram image obtained from the longest foot in 188 schoolchildren. Results: By default, the footwear was poorly fitting in length (too short or close-fitting) in 38.5% of the schoolchildren, with boys having the worst footwear fit; though no significant differences stood out. (<i>p</i> = 0.276). Regarding the HVA, no significant differences were recorded according to age or gender (<i>p</i> = 0.573). A strong correlation was observed between too-short footwear and the increase in HVA in 10-year-old boys (<i>r</i> = 0.817; <i>p</i> = 0.025) and in 9-year-old girls (<i>r</i> = 0.705; <i>p</i> = 0.005). Conclusions: Inadequate footwear fit in length may be a predisposing extrinsic risk factor for the development of hallux valgus in schoolchildren of both sexes. Results of the present study demonstrate the need to adapt the sizes of footwear to the rapid increase in foot-length that occur at puberty to avoid the risk of developing hallux valgus, especially at the ages of onset pubertal foot growth.María Luisa González-ElenaAurora Castro-MéndezManuel Coheña-JiménezAntonio Córdoba-FernándezMDPI AGarticlefootwear fithallux valgusfeet deformitiesindoor shoesschoolchildrenfunctional length excessMedicineRENInternational Journal of Environmental Research and Public Health, Vol 18, Iss 11244, p 11244 (2021)
