Focus on Every Detail

S-PHYRE

S-PHYRE is our flagship racing line that combines scientific-guided designs with professional insights to help you pedal harder, race faster, and see clearer.

Built for performance

Anti-twist stabilizing structure within the heel cup offers unparalleled stability during explosive sprints. DYNALAST technology secures your foot in place, reducing power loss at the pedal and lessening fatigue during long rides, while the optimized toe-spring section reduces tension in your feet, calves, and hamstrings - so you can go further, faster.

Exceptional fit

How a shoe fits and feels defines its performance. The RC903 takes both to the next level with a 360º surround wrapping upper, a refined toe box fit, and a low-profile crossover lacing pattern with two BOA® Li2 dials for the most precise fit possible.


Media Reviews

"Best all-around race shoe"
"The Shimano S-PHYRE RC9 shoes have been a favorite of many testers on the Cycling Weekly Tech Team."

"The sole is impressively stiff, flexing only 1.4 millimeters in our in-house deflexion test."
"This is a high-performance shoe that makes no deliberate performance sacrifices for the sake of increased comfort, yet we’ve found that it feels impressively easy to wear and light on our feet."
"The Shimano S-PHYRE RC903 is a gorgeous shoe that does a great job holding your forefoot right where it should be."

"Vertical space in the front end of the shoe is ample, giving the toes plenty of space to breathe and never feel squished from above. This gives the S-PHYRE RC903 the slipper-like feeling over the top of the midfoot that so many cyclists love."

Amazing Shoes

"I am a 65 years old cyclist who picked up road cycling for the second time in life after turning 52 years old. During this period I was not willing to spend more than 250 dollars on bike shoes. I have to admit that I was making a bad mistake. These top tier Shimano shoes just helped me improved my pedaling quality in a remarkable way, specially when out of the saddle. Also, I am amazed by their power transfer. So much better! Great shoes without a doubt!"

Q&A

I received the shoes with medium and high arch insole pads. Are there low arch/flat foot pads, should I ride without the pads installed, or should I seek third party insoles?
Hello Tim, Using just the insole with none of the arch support pads will be the base low support fit.
How is the fit on these new model? The last one was very tight even wit the wide version. Is it true to size?
Hello Jose, The RC903 upper is completely different pattern and new material. The new upper material is microfiber leather that is more elastic and accommodating but still very supportive and snug fitting. The toe box are has also been re-shaped to be more round and curved and less pointy, to allow a bit more toe room. Both of these updates are intended to improve the fit and accommodate a broader range of foot shapes. The sizing should be more in line with the RC901 and true to size.
