Constructed using groundbreaking midsole foam developed in the ASICS Institute of Sports Science, FlyteFoam® technology isn’t just a little bit lighter - it’s remarkably 55%* lighter than the industry standard. Midsoles constructed with FlyteFoam® tech aren’t just super lightweight, either: They benefit from organic “super fibers” that bounce back into their original shape in the space of each stride, providing perfect adaptive cushioning from the start of your run to the finish. This engineered resilience also makes midsoles with FlyteFoam® technology far more durable than their predecessors, so your body benefits not only from an elite level of cushioning, but elite cushioning will perform at its peak longer and stronger than ever before.
