As Michael Phelps looks to add to his unprecedented 22 Olympic medals in Rio, he'll be walking around Brazil in a pair of 3d printed shoes from Under Armour.
The athletic apparel giant, which has quite a bit of experience 3d printing sneakers, created a custom shoe for the world's most famous swimmer which includes the footprint of his baby soon Boomer on the shoe's outer sole, with a 3d printed insole made to fit Phelps' feet.
The design of his son's footprint on the UA Arcitech shoe is “a personal reminder that Boomer is with him every step and stroke of the way,” according to Under Armour.
"The UA Architech is a 360-degree performance training shoe that features a functional 3D printed midsole and 3D ClutchFit auxetic upper design that creates a 'super-hybrid' trainer," the company says. "The innovative 3D printed midsole of the UA Architech was combined with a flow-molded 3D ClutchFit auxetic upper to provide athletes with a shoe that not only gives a locked-in, supportive feel, but also flexes and moves with the foot to provide a zero distractions experience."
Under Armour released a limited edition set of 3d printed sneakers earlier this year but this is the most high profile release of 3d printed sneakers to date.
