When every watt matters and every adjustment counts, the all-new S-PHYRE SH-RC910 shoe represents the next evolution of SHIMANO’s flagship road racing shoe. Engineered as a complete pedaling system alongside the new SPD-SLR pedal platform, the shoe is designed for the world’s fastest riders and refined through extensive WorldTour feedback. The S-PHYRE RC910 delivers exceptional power transfer, an even more precise fit, and the lowest stack height Shimano has ever produced.

Sizing Note

Riders who currently wear a Standard fit can expect a roomier toe box, while those who previously sized up for extra width or toe room may prefer to size down by ½ size for a more precise fit. The new SHIMANO DYNALAST 2.0 Wide fit is noticeably roomier than both the previous DYNALAST Wide and Standard fits, offering increased width and a larger toe box. Women riders and anyone who prefers a snugger, performance-oriented fit may find the Narrow option provides the best fit.

Choosing the Right SHIMANO DYNALAST 2.0 Fit

Standard

If you've been happy with the fit of your current Standard DYNALAST shoes, the new Standard fit will feel familiar through the midfoot and heel while providing noticeably more room around the toes for improved comfort on long rides.

Wide

If you've worn Wide DYNALAST shoes in the past, be aware that SHIMANO DYNALAST 2.0 Wide is significantly wider than the previous Wide fit. Riders who truly need extra forefoot volume will appreciate the increased width, while others may find that the new Standard fit now provides all the room they need.

Narrow

Riders who previously rode SHIMANO's Women's-specific models or those who prefer an especially snug fit will generally find that the new Narrow fit offers the closest equivalent. The Narrow last maintains a lower-volume fit while benefiting from the updated toe shape and improved forefoot comfort introduced with SHIMANO DYNALAST 2.0.

Maximum Pedaling Efficiency

The S-PHYRE RC910 features a redesigned carbon hollow core sole that lowers the distance between your foot and the pedal axle, creating Shimano’s lowest stack height ever. The result is a more connected ride feel, improved pedaling efficiency, and more direct power transfer with every pedal stroke.

Precision Fit from Front to Back

Featuring the new SHIMANO DYNALAST 2.0 platform, the RC910 has been completely refined to match the shape of riders’ feet better. A wider forefoot, optimized toe box, and reduced toe spring decrease pressure across sensitive areas of the foot while maintaining the secure locked-in feeling demanded by professional racers.

The perfect shoe

"I’ve been loving the new Shimano 910s! The fit, comfort and overall feel have been fantastic. One of the most noticeable improvements for me is the availability of narrow sizing. Having the option to get a shoe that actually fits a narrower foot makes such a difference in comfort, stability and overall performance, especially on longer rides. It’s great to see Shimano offering more sizing options rather than a one-size-fits-all approach. Overall, a fantastic upgrade and a shoe I’d highly recommend!"

— Lauren J. (5/5)

Great shoe, but….

"Made the switch from the 903 to the 910. Love the shoe, but there is to much material in the upper. It causes a crease that puts pressure on the top of the foot. I’m hoping as the wear in this will subside. The 903 is the best shoe I have worn"

— Chad M. (3/5)

Love the feel

"The shoe takes way less time to break in than the previous version. I really like the 3rd option. I will say that it does size up 1/2 size though. So while I used to ride a 45.5 I ended up with the 45 and that fits the same as the old 45.5. Shimano was super easy to work with on the return and getting me a new pair. So for that I give them a 5 star."

— Eric W. (5/5)

Finally wide is wide

"Wide fit for wide feet. Excellent shoe, fit even better now that a true wide is available. Upgraded from 903 worth every penny."

— Ronald t. (5/5)

Seem a little bigger than previous model

"Love that the tightening clip does not solely rest on my 5th metatarsal, they moved it a few mm up which is great. However, they seem a bit longer than my current 44w. If I buy another pair I will size down 1/2z"

— Michael M. (4/5)

Too small.

"Ordered a 1/2 size smaller. Too small. A lot of money."

— Thomas A. (1/5)

Finally, the S-Phyre fit more riders have been waiting for...

"I put roughly 8,000 miles on the RC903 in size 43. I loved the shoe, but my biggest complaint was the narrow forefoot: as my feet expanded during rides, my toes would start feeling squeezed and I routinely had to loosen the front BOA--sometimes 30 minutes in, sometimes several hours in. And I don't even have wide feet. They're relatively narrow. For the RC910, I ordered four sizes to get it right: 43 Standard, 43 Wide, 43.5 Standard, and 43.5 Wide. I ultimately kept the 43.5 Wide, and the new fit is a major improvement. The wider toe box finally gives my forefoot room to expand without losing the secure lock down. Shimano says the RC910 fits roomier, but I still personally preferred the 43.5 as opposed the 43 in my A-B testing. I think the Wide RC910 will be especially popular. Shimano shoes have had a combination of performance, function, and aesthetics, but the narrow RC903 fit simply didn't work for a lot of riders. The RC910 opens that door considerably. Also worth mentioning: Shimano's return process was painless. As long as I didn't install cleats or ride the shoes, returning the other three pairs was straightforward and easy. Bottom line: If you liked everything about the RC903 except the cramped forefoot, the RC910 Wide is absolutely worth trying. 5/5 Shoes 3/5 Value (it's relative)"
