FlyteFoam Midsole Technology - Our FlyteFoam technology provides exceptional bounce back and responsiveness no matter the distance, utilizing organic super fibers to help reduce packing out that traditionally happens with softer, low density foams. Rearfoot and Forefoot GEL Technology Cushioning System - Attenuates shock during impact and toe-off phases, and allows movement in multiple planes as the foot transitions through the gait cycle. Guidance Line Midsole Technology - Vertical flex groove decouples the tooling along the line of progression for enhanced gait efficiency. Seamless Construction - The use of seamless materials reduces the potential for irritation and friction caused by traditional stitches and seams.
