No matter how long or short our ride, the SIDI Prima Mega Road Shoe keeps us comfortable for the duration of our time in the saddle. The lightweight upper construction sits comfortably against the top of our foot, while the low-profile carbon/nylon Aerolite sole keeps the bottom supported and free of fatigue. For a secure fit that allows us to put maximum power into the pedals, we twist on the dial of the Firmore closure system and secure the hook-and-loop strap.
