When you are the tallest man in the US, finding a new pair of shoes is not as simple as popping down the road to the shops.
For Igor Vovkovinskiy, who stands at 7ft 8in tall (2.34m) and is between a 22 and 25 size shoe, it will take weeks to perfect the fit.
The 29-year-old, who is originally from the Ukraine, has had 15 operations over six years to fix problems created by shoes that did not fit.
But Reebok are now designing a pair of shoes to end his struggle, at the cost of up to \$20,000 (£12,300).
Mr Vovkovinskiy had to have a complex fitting that involved custom pressure-mounting equipment, bio-foam, a device that takes precise measurements of length, a tape measure and several technicians.
Reebok will spend around six weeks creating prototypes to try and will then fine-tune them to produce proper-fitting shoes.
Mr Vovkovinskiy claims his only current shoes have no traction, making it "suicidal" to leave his home.
"I haven't been able to go for a joyful walk for six years now," he said. "I look forward to just going for a walk with my dog, just walking around the neighbourhood."
"Basically, I'm a prisoner of my own house, even though I am medically cleared to walk.
"Where am I going to go with shoes that are painful?"
Mr Vovkovinskiy is originally from the Ukraine but moved to Minnesota aged seven so that he could get treatment for his condition, known as pituitary gigantism.
He had to spend three years resting in bed after surgery and said: "Living the last six years has been a nightmare basically."
