The RC810 takes the shape, the closure and the fit of the S-PHYRE RC910 and brings them down a price point. It is aimed at riders who want genuine race-shoe stiffness and hold without paying for the flagship sole, and it closes most of the gap that used to sit between the RC703 and S-PHYRE.

The sole is solid carbon prepreg, heat pressed, rated stiffness index 11, with the same seamless midsole structure and the same SPD-SLR cleat adjust range as the RC910. That matters: the cleat sits in the new rearward position without the sole getting thicker, so you keep the low stack height that the SPD-SLR system is built around. The replaceable heel pad is shared with the RC910, and the same +5mm taller service pad fits if you prefer a little more height when you put a foot down.

Up top it is a surround wrapping upper with the honeycomb graphic treatment borrowed from the RC910, in a lighter and more breathable build than the RC703 it replaces. Two BOA Li2F dials handle the closure, using the new lace profile that now runs across every size. Inside is Shimano Dynalast 2.0, so the forefoot is noticeably roomier than the old standard last while the heel and instep stay locked in.

Available in White and Black, in narrow, standard and wide fits.
