Shimano's New Road & Gravel Shoe Range: S-PHYRE RC910 vs RC810 vs RX710 Compared

Quick answer: Shimano has refreshed its road and gravel shoe range around a new last called DYNALAST 2.0, which widens the toe box (up to 7% more volume in Wide fit) and adds a Narrow fit option for the first time. The flagship S-PHYRE SH-RC910 is built with a carbon heel cup and engineered specifically around Shimano's new lower-stack-height pedal system, for riders who want the outright fastest setup. The SH-RC810 shares the same DYNALAST 2.0 platform and pedal compatibility at a more accessible tier, with an external heel stabiliser instead of a carbon heel cup. The SH-RX710 is a separate mid-tier gravel shoe update, using its own Pontoon cleat system rather than the new road platform.

What’s new?

Three shoes are updating at once, but they split into two separate stories. The S-PHYRE SH-RC910 and SH-RC810 are road racing shoes built on Shimano's new DYNALAST 2.0 last and engineered to work with the new SPD-SLR pedal and cleat system launching alongside them, so fit and pedal performance are designed together. The SH-RX710 is a gravel shoe update running on its own Pontoon cleat system, so treat it as a related but separate release rather than part of the same stack-height story.

DYNALAST 2.0: the last behind RC910 and RC810

Both new road shoes are built on a new last (DYNALAST 2.0) with three fit options: Narrow, Standard and Wide. The forefoot was the primary focus of the redesign, letting the toes splay naturally for better balance and stability. Compared with the previous-generation Dynalast (measured on a size 43 in both), DYNALAST 2.0 adds 2mm of width at the ball of the foot and 3mm at the tip of the toe, which translates to:

• Standard fit: 4% more toe box volume than the previous generation
• Wide fit: 7% more toe box volume - 6mm wider than the previous generation
• Narrow fit: new to the platform, for riders who want a closer fit through the forefoot

Beyond width, DYNALAST is built with anatomical heel and toe spring curves that follow the foot's natural shape, rather than the flatter heel and more aggressive toe-spring curve common on other lasts. The intent is less tension through the foot over a long ride, with flex and rebound tuned to each pedal stroke. Fit is assessed across three reference points: the instep (secure without restricting blood flow), the ball (the main reference point for choosing Standard, Wide or Narrow), and the toe (where the broader DYNALAST 2.0 shape allows natural splay).

S-PHYRE SH-RC910 vs SH-RC810: what's the real difference?

Both shoes give you the same fit platform and the same pedal compatibility, so the decision mostly comes down to stiffness and budget: RC910 is the stiffer, lighter, carbon-heel-cup flagship for riders who want the outright fastest shoe; RC810 gets you the same last, the same pedal system and most of the fit benefit at a more accessible price, with a slightly less stiff ride and an external rather than carbon heel stabiliser.

SH-RX710: the gravel update

The SH-RX710 is a mid-tier gravel shoe running its own Pontoon cleat system rather than the new road SPD-SLR platform, so it's a related seasonal update, not part of the pedal/cleat/road-shoe ecosystem story. It's already available, ahead of the road launches.

FAQ

What's the actual difference between the S-PHYRE RC910 and the RC810?
Both share the same DYNALAST 2.0 last and the same next-generation SPD-SLR pedal compatibility. RC910 is stiffer, lighter, and uses a carbon heel cup with anti-twist stabilisation; RC810 uses an external heel stabiliser instead, isn't quite as stiff, and sits at a more accessible price.

Do the new shoes work with my current Shimano pedals?
The RC910 and RC810 are built around the new next-generation SPD-SLR pedal and cleat platform launching alongside them. If you're running older Shimano pedals or a third-party system, check pedal/cleat compatibility before buying, the full breakdown is in our pedal and cleat guide here.

Is the SH-RX710 gravel shoe compatible with the new road pedal system?
No, the RX710 uses its own Pontoon cleat system, separate from the new SPD-SLR road platform used by RC910 and RC810.

What fit options are available on the new shoes?
DYNALAST 2.0 (used on RC910 and RC810) comes in Narrow, Standard and Wide. The RX710 gravel shoe is also offered in Standard, Wide and Narrow.

When can I buy the new S-PHYRE RC910?
Preorder is open now for delivery from the first week of October. The RC810 is in stock 25th September, and the RX710 gravel shoe is already available.
