SD standard deviation. Response options: for items 1–11, 1 = Conventional footwear is much better to 5 = Therapeutic footwear is much better, where 3 indicates indifference; for items 12–13, 1 = Highly improbable to 4 = Highly probable. † Variables with p-values < 0.10 in the univariate analyses were entered in the multiple regression analysis. * p < 0.05 in the multiple regression analysis
