The Shimano RC810 road cycling shoe pairs a low-stack carbon sole with the DYNALAST 2. 0 last, shaped with a wider forefoot and reduced toe spring for a more natural fit through the pedal stroke. This build uses the wide width for riders whose foot spreads out under load rather than staying narrow through a full ride. Dual BOA Li2F dials cinch the upper down with independent forefoot and midfoot pressure, and a reinforced heel cup keeps the foot locked in through hard accelerations out of the saddle. What Our Gearhead(R) Experts Are Saying:"My feet swell a full size into a long ride, and the wide RC810 is the first race shoe I've worn where I don't have to loosen the dials at mile fifty just to keep feeling in my toes."
