Revolution of the speciesThe Factor™Techlace™is a race-bred cycling shoe that couples the benefits of our Techlace system with the easy adjustment of a Boa® dial, plus the performance you expect from Giro—all at an impressively low weight of 210 grams (size 42.5). The Techlace system replaces D-rings and other hardware with laces, providing a more supple feel across the forefoot, and the laces can be easily replaced if damaged. The Boa® IP1 dial offers fast, intuitive adjustment in 1mm increments when tightening or loosening. The Factor Techlace upper is constructed with Evofibre SL, which is durable yet highly breathable. Inside the shoe, our Super Natural Fit foot bed features adjustable arch supports to personalize fit, comfort and pedalling efficiency. Power transfer is bolstered by the Easton® EC90 SLX2 carbon fibre outsole, which is among the lightest, thinnest and stiffest pedalling platforms on the road, giving you a direct connection to the pedals.UPPER:One-piece upper designPremium Evofibre™SL breathable Teijin® microfibre Techlace™+ Boa® IP1 dial (1mm +/- with macro release)OUTSOLE:Easton® EC90 SLX2 high-modulus carbonSteel hardwareReplaceable heel padsFOOTBED:Super Natural Fit Kit with adjustable arch supportX-Static® anti-microbial fibre Travel bag includedWEIGHT:210 grams (size 42.5)SIZING:40 - 48
