Random thread, my son is 13, he has size 13 adults feet! I feel this is unusual and struggle to get certain trainers/shoes in his size, do you think his feet will stop growing here as he is way above a average mens size anyway? When weve looked at trainers online they mostly only go up to a 13 ( and normally dont have the stock in that size) would we have to shop in specialist shops if he didnt stop growing? Hes pretty tall about 6 foot. Whats the biggest size feet you know of?
