Redefining fit, feel and power-to-weight performance, the Prolight SLX II are the lightest, most powerful, pro-level road shoes Giro has ever created. New Evofiber Microfiber upper is water-repellent, highly breathable and conforms to your foot like a second skin for effective energy output. Ultralight footbed, plus the Ultralight SuperNatural Fit Kit footbed with adjustable arch support enhances comfort, efficiency and allows for a truly custom fit. Updated Easton EC90 SLX ACC high-modulus carbon outsole with a 6.5mm profile is nearly weightless and delivers best-in-class stiffness for maximum power transfer. Pressure-free, low-profile closure system with titanium straps and hardware reduces weight even further. The Prolight SLX II shoes are the most natural and direct connection to the pedals you can get.
