I kniw I am-I'm a mummy and should have figured this stuff out by now. So I recently took the eldest for his regular foot measurement (paranoid about him wearing ill fitting shoes). He's been measured as a 10 on one foot and a 10 and a half in the other. He is currently wearing size 10 shoes. What am I supposed to do? Do I buy a 10 1/2 shoe or do I wait for his biggest foot to reach size 11 and buy size 11 shoes. He's not complaining if any pain or tripping over so I am tempted to just wait but I don't want to harm his feet. Are you actually supposed to buy half sizes and full sizes or is it just a case of giving you more choice? Why don't children come with an instruction manual?
