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.
Giro's proprietary, advanced carbon composite outsole plate ensures efficient power transfer and responsive feel at the pedals while allowing 5mm of adjustment for optimal cleat positioning. It's the ideal balance of stiffness and durability with light weight.
The BOA® L6 Fit System provides fast micro-adjustability with the turn of the dial. The combination of the dial, lace, and guides reduces weight and provides finer adjustment (1mm increments) compared to traditional buckles, and it offers an instant release function, too. BOA Fit System dials and laces are guaranteed for the lifetime of the product.
