• Synchwire construction is a stitch-less upper that's vented and reinforced to create a lightweight cycling shoe with incredible airflow and structural integrity. Synchwire is an advanced composite of thermo-bonded film that provides overall durability, a non-woven internal sheet for distributing the force from the closure system to the upper for direct power transfer, and mono-filament mesh for ventilation.
• Our Easton-engineered outsole features EC90™ high modulus carbon for class-leading stiffness- to-weight, with a flat perimeter edge that allows your foot to conform naturally to the shoe's upper for greater comfort.
• The Giro SuperNatural Fit System includes an adjustable arch support kit with Low, Medium, and High arch supports. You can adjust arch support to enhance fit and pedaling efficiency while reducing the chances of common discomforts like hotspots, numbness, and cramping.
