Research shows that ill-fitting shoes can negatively impact the development of the pediatric foot, in a very direct manner. The primary aim of the study was to determine if the dimensions of available prescribed school shoes fit the foot dimensions of habitually barefoot South African children and adolescents.
A cross-sectional observational study was conducted where static standing foot measurements of children and adolescents from urban and rural schools were obtained with a mobile caliper. The maximum heel-toe-length and foot width with an added 10 mm toe- and width fit allowance to each participant, were compared to the corresponding school shoe length and shoe width available in retail. A mixed model ANOVA was used to compare foot dimensions between gender, age and side.
Six hundred and ninety-eight school children (N = 698) (431 girls; 267 boys; average age 10.86 years, SD = 2.55) were participants. A total of seventy-seven (N = 77) black coloured prescribed school shoes currently available in retail ranging from different styles and brands were measured. Results show that, comparing the shoe length and maximum heel-toe-length of participants, as well as taking 10 mm toe allowance into account, fifty-nine percent (59%) of children wore shoes that were not the correct length. With regards to the shoe width and the added 10 mm of width fit allowance, ninety-eight percent (98%) of the shoes worn by participants were too narrow for their feet.
Results confirmed that school shoes currently available in retail, are not suited for the habitually barefoot population studied. It is recommended that the shoe manufacturing industry should consider the shoe width of school shoes for children and adolescents in habitually barefoot populations to avoid the long-term negative effect of ill-fitting shoes on the pediatric foot.
研究表明，不合脚的鞋子会对儿童足部的发育产生直接的负面影响。本研究的主要目的是确定现有的处方学校鞋的尺寸是否符合习惯赤脚的南非儿童和青少年的足部尺寸。
进行了一项横断面观察性研究，使用移动卡尺获取城市和农村学校儿童和青少年的静态站立足部测量值。将每个参与者的最大足跟-足尖长度和足部宽度加上 10 毫米的脚趾和宽度适配余量与零售中可用的相应校鞋长度和鞋宽进行比较。使用混合模型方差分析比较性别、年龄和侧别之间的足部尺寸。
共有 698 名在校儿童（N=698）（431 名女孩；267 名男孩；平均年龄 10.86 岁，标准差=2.55）参与了研究。共测量了目前在零售中可用的 77 双（N=77）黑色处方校鞋，涵盖了不同款式和品牌。结果表明，比较参与者的鞋长和最大足跟-足尖长度，以及考虑到 10 毫米的脚趾余量，59%的儿童穿着不合脚的鞋子。至于鞋宽和增加的 10 毫米宽度适配余量，98%的参与者所穿的鞋子对他们的脚来说太窄了。
结果证实，目前在零售中可用的校鞋不适合本研究中习惯赤脚的人群。建议鞋类制造行业应考虑习惯赤脚人群中小学生鞋的鞋宽，以避免不合脚的鞋子对儿童足部的长期负面影响。
