The Factor Techlace is a sleek racing shoe that combines the advantages of Giro's Techlace system with the easy adjustment of the Boa dial, along with the performance you expect from Giro. All this comes at an impressively low weight of 210 grams per shoe (size 42.5). The Techlace system replaces D-ring eyelets and other components with laces, providing significant comfort in the forefoot area. The Boa IP1 closure allows for quick, intuitive adjustments in 1 mm increments when putting on or taking off. The Factor Techlace upper is made from Evofiber SL, which is highly breathable and durable. Inside the shoe, the Supernatural Fit insole ensures optimal arch support and maximum comfort while riding. Optimal power transfer is guaranteed by the Easton EC90 SLX2 carbon fiber sole, which is among the lightest, thinnest, and stiffest on the market.
