Asics Gel-Kayano 31 men's running shoes offer a stable running experience and responsive underfoot feel. Featuring a low-profile outer heel insert, they comfortably cradle your foot with extra support at the back of the foot. The midsole, with its FlyteFoam BlastTM Plus Eco cushioning, helps keep the shoe light while delivering a more energetic bounce with every step. What's more, the 4D Guidance SystemTM technology, positioned on the inner corner of the midsole to reduce pronation, offers a more sustained stride while preventing your foot from rolling too far inward. Comfortable, these shoes feature a versatile, functional design and their breathable mesh upper is made in part from recycled materials. They are colored using a dyeing process that consumes less water than the traditional process.
