Constructed from an innovative engineered 3D knit fabric to create a one-piece seamless upper that is light and breathable, moisture is effectively managed and there are no unwanted pressure points. The knit fabric flexes and conforms to the riders foot for maximum comfort and a customised fit, and a BOA Fit System offers fast micro-adjustability for a perfect fit. With 3-bolt cleat compatibility, this stiff sole is engineered using super supportive Anatomic Carbon SL which provides race-winning energy transfer, and the reinforced heel gives you off the bike traction.
