High Volume Fit

Giro “HV” footwear is built on proprietary, cycling-specific lasts that are specially designed to create a fit that hugs wider or higher-volume feet closely without binding, crowding or discomfort. In order to provide the most supportive and precise fit possible, our HV lasts are hand-crafted in whole and half-sizes too, so you get the best fit possible in a production shoe. Giro HV fit is recommended for widths from D-EE, and is an option for feet with very high instep.


X-Static FIBER – X-Static fibers use natural silver to provide heat conductive and anti-microbial properties to help keep your hands warm, and your gloves free of odor-causing bacteria and fungus

Easton® Carbon Composite Outsole

Unidirectional carbon fiber outsole is engineered to provide a direct connection with the pedal, thanks to class-leading stiffness that puts full effort into forward motion


A superb fit, with adjustable arch support to help optimize comfort and enhance pedaling efficiency.
