Not even you knew you could be this fast. The ULTRA ULTIMATE Women's Fit combines new, ultra-lightweight ULTRAWEAVE upper and redesigned soleplate tooling with measurements such as volume and instep height all engineered for the female foot. The gravity-defying ULTRAWEAVE upper is reinforced with PWRPRINT technology to provide micro level stability and support. Built on a sleeker and more aggressive last, the chassis of the boot has been enhanced with a new dual density SPEEDPLATE outsole engineered for rapid propulsion.
