X-Frame® by Northwave is an innovative design engineered to transfer every watt of power while providing the snuggest, even fit with no pressure points.
Totally unique, it combines next-generation materials that are only 0.5 mm thick and ultra soft for exceptional comfort with a structure featuring 360° reinforcements along the length of the foot that connects the sole to the laces via the upper.
The SLW2 dial closure system works with the X-Frame design, replacing plastic inserts with soft tapes, while the soft, flexible Dyneema cable naturally conforms to the shape of each foot.
A snug fit and perfectly balanced closure that pulls evenly around the entire foot from toe to instep. Kudos goes to the innovative route taken by the cable through special tapes: it passes through a complex system of angles and geometric precision made possible purely by relentless testing on countless prototypes.
