The Prolight SLX redefines fit, feel and power to weight performance in a lightweight shoe. Starting with a select Teijin microfiber upper that shapes to your foot like a second skin, we added an ultralight EVA footbed plus a SuperNatural Fit Kit footbed with adjustable arch support so you can customize the fit to match your needs. At only 6.5mm thick, the high modulus Easton EC90 SLX outsole is exceptionally thin and light yet provides best in class stiffness for maximum power transfer. Titanium hardware reduces weight even further. If you're looking for the lightest pro level shoe without compromise, this is it.
