Originally designed in conjunction with the ASICS Institute of Sports Science (ISS) in Japan,the METARUN™ SPS shoe originally debuted as a long distance running style to help runners go farther,while making a breakthrough in technology and comfort. FLYTEFOAM® technology in the midsole is 55% lighter than industry standard EVA foams,while the ADAPTTRUSS™ technology,METACLUTCH™ technology and X-GEL® technology work in unison with each other to promote lightweight stability and energized cushioning.Equipped with the same advanced componentry that’s made to assist long distance runners,the METARUN™ SPS shoe is equally suited to stomp the streets with a blend of sportswear and technical design nuances.
