CloseUnder Armour Speedform Running Shoe
To create the completely seamless heel cup in the Under Armour Speedform, designers headed to an unlikely place: a bra factory. Intimate-apparel makers are very aware that a close fit is key to comfort, and it's those manufacturing techniques that allow this running shoe to be stitch free from heel to toe, every section ultrasonically welded together for a snugger fit.
