In addition to the state-of-the-art technology and custom colour design, USA’s elite swimmer Michael Phelp’s footwear features a personal touch to provide an additional source of motivation as he heads into competition at the Rio Olympics.

His 3-month old son, Boomer’s footprint is printed on the insole of the shoe as a personal reminder that Boomer is with him every step and stroke of the way.

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.

Add in the Brand’s unparalleled Charged Cushioning underfoot for responsiveness and comfort, and a thin rubber outsole for traction and you have Under Armour’s most elite performance trainer.

A new colour of the UA Architech will be available as a limited edition offering to consumers in August on UA.com and Under Armour Brand House locations. The shoe, which retails for $299.99, was the first 3D printed performance trainer available to consumers. The first colour was available in March and sold out in under 20 minutes.

Under Armour also geared Michael up with a custom pair of the UA Speedform Slingshot Running shoes in a limited edition red, white and blue colorway that also feature Boomer’s footprint. This innovative running shoe delivers zero distractions with a seamless, zonal compression, 3D knit upper and Under Armour Charged Cushioning. The limited edition colour way is available on UA.com.
