Upper: A lightweight engineered knit upper gives you plenty of breathability, style and comfort. There is a new and improved midfoot hold to create a more supportive fit. ASICS updated the knit collar construction which improved the fit and feel and made it easier to put on as well.
Midsole: The FF Blast™ Plus Eco is a light and energetic foam that provides you with a soft and plush ride. There is Puregel™ at the heel which provides additional cushioning, is lighter weight and is 65% softer than conventional visible GEL™ technology. It also has 24% bio content to make its construction sustainable.
Outsole: A new hybrid outsole combines ASICSGRIP™ and AHAR™ outsole rubbers to give you better traction and improved softness, while still being durable enough to keep up with your miles.
