The ISOFIT lacing system adapts to different foot shapes to provide a personal and secure fit everytime you run. Designed with ISOFIT technology the soft inner sleeve is made from stretchable mesh fabric for a sock-like comfort fit. The second component is an outer support layer engineered to both adapt to a wide range of midfoot shapes and to move with the foot through every flex. The dynamic nature of the materials combined together with the independently adaptive fingers, securely hold the foot in place over the sole, for a snug, secure fit that moves and flexes with you through very stride for a smooth, distraction free ride.
FORMFIT and PWRFOAM Midsole
The FORMFIT performance midsole is created using a dynamic 3D cradle to fit, cushion, and support a wide range of foot shapes made to hug your foot every step of the way. The midsole is engineered with 3 layers of foam; the top layer consists of a soft sockliner made to create a customised contact surface area along the entire foot. The middle layer is engineered with an EVERUN topsole; 3 x more durable and 3 x less temperature sensitive than EVA the EVERUN topsole allows for a constant response that is made to last run after run. With 83% energy return the EVERUN topsole gives you the lively boost you need that adapts to your foot’s unique pressure pattern and smooths your forward role. Finally the EVERUN topsole is twice as flexible as standard cushioning moving with your foot for smooth landings, stable transitions, and powerful take offs. The lower layer of the midsole is contoured to cradle your foot, while absorbing impact from initial ground contact to protect joints and giving you the right amount of spring for your step. PWRFOAM resides in the midsole to provide durable underfoot cushioning and comfort. This winning combination means your use of superfluous muscle power is reduced, diminishing fatigue and enhancing performance, keeping you motivated for longer.
