adidas footwear is about to fit better than ever thanks to the German sportswear giant’s latest technological breakthrough: FORGEFIBER. An innovative new stitching technology inspired by body movement and the exploration of how organic cell structures grow. Utilizing TPU-coated yarn that’s then stretched and heat compressed in targeted zones, FORGEFIBER provides 30% more resistance than your average construction and can behave in a variety of ways — depending on the sport — thanks to changes in the density and angles of the stitching. The result is a design that not only offers more support while using less thread, but one that fits more precisely, too.

“Every sport is about movement and every athlete is unique,” said Jon Munns, senior design director on the adidas Future team. “They all have different needs and when we are designing products for them, we are trying to create the very best for them to support their movement.” Designer Jason McGinnity adds:

Running is more about linear movement. The super flexible and strong FORGEFIBER upper for a runner will provide enhanced lockdown and stability in the midsole for a smooth gait cycle. For basketball we want to be much more prescriptive in certain areas of the shoe, like on the lateral for heavy cutting… The adaptable design process can easily address different performance needs while still allowing breathability and comfort. As we look toward the future, possibilities of where we can take this are unlimited.

FORGEFIBER will debut on a limited edition “Core Black” colorway of the alphabounce, which is set to drop later this month via for $140 USD.
