ASICS' triathlon staple shoe, the Noosa FF 2 has been reinvented with revolutionary FlyteFoam(R) Technology to create a responsive and lightweight ride. The seamless upper construction features a technical mesh that permits sockless wear, while the wet-grip outsole and heel/tongue grips allow for easy on/off access - ideal for triathletes looking to make a quick transition between race stages. Features: - Best for neutral runners. - HG10MM(R) Heel gradient shifts body mass forward, reducing strain on lower limbs. - 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. - Independently placed eyelets disperse lace tension, creating a customized fitting environment and enhanced upper comfort. - Seamless materials reduce the potential for irritation and friction caused by traditional stitches and seams. - Rearfoot GEL cushioning system attenuates shock during impact phase and allows for a smooth transition to midstance. - Wet Grip(R) outsole made from a special blend of organic and non-organic components, designed to enhance traction even on wet surfaces. - Weight: 7.2oz. - Heel Height: 23mm. - Forefoot Height: 13mm.
