Built to deliver maximum comfort and stability. Great for long runs, because the Quikspring+ platform features extra volumes of Quikfoam to deliver more comfort. Together with the medial post, the Quikspine structure under the midfoot provides stability for those who over-pronate. The upper features a very comfortable Morphit cradle around the midfoot, with reinforced support on the medial side of the foot. Other features of the upper are the invisible athletic toe which reduces toes to rip through the upper, a super comfy heel cradle and the Ortholite insole which provides extra comfort and breathability.
