hi just took my 14 month old daughter for her first walking shoes and been told she has a high instep.does anyone have any explanation as to what this is? as if i want to buy shoes what should i look for if she has this....also does anyone know where and if i can buy my own foot measure for her.they tell me to go every 8 weeks to have them measured,but i thought i could do it myself then if theres a change i could take her for new ones.at least thenid know myself if theres been a change...any tips would be greatful
