I tried to buy DS (10) some shoes and socks today, none of the children's shoes or socks on sale in 4 different shops went up to his size so I've had to buy adult's trainers for him! The socks are 4-6 so I hope they fit his 6 1/2 feet or the alternative is men's size 6-11 which are going to swamp him. Surely shops expect boys to have larger than 6 1/2 feet before they want adult shoes!
