This 15-year-old schoolboy is on track to have the largest feet in Britain.
Sam Preston already wears a size 19 shoe - bigger than Olympic swimmer Ian Thorpe and footballer Peter Crouch - but he is still growing and is set to break the current record of size 21.
And the 6ft 6in teenager said his unusually-large feet don't go unnoticed, with strangers often stopping to snigger and stare at him on the street.
Sam, from Wantage, Oxfordshire, said: 'I hate when people talk behind my back. I hear groups of people whispering stuff like "Ronald McDonald called and asked for his shoes back".'
And while his father and 21-year-old brother, Josh, wear a size 12 and 11 respectively, Sam's mother, Leigh Deakin, 43, said her son has always been larger than average.
She said: 'He has always been big - he weighed 11lbs when he was born. We first realised he had larger than normal feet when we bought his first shoes.
