The Storm Carbon 2 Cycling Shoe features several technologies that combine comfort, stiffness, and performance to create the perfect shoe for long days in the saddle. Constructed with a Morph Carbon 12 AAS sole, a full-carbon insert, and Anatomical Arch Support made with TPU, the Storm Carbon 2 sole adapts to any foot shape while maintaining a stiffness index of 12. 0. An asymmetrical lacing system relieves pressure from the top of the foot and works together with the SLW3 dial and extra strap to ensure a snug fit and optimal stability.
