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.
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.

"Shoe is amazing, quality and weight. the sizing ran bigger than the measurements."
"The shoes are a fantastic upgrade from my previous pair. The fit is spot on, and I really appreciate how responsive they are and how seamlessly they make my leg feel connected to the bike."
"Too narrow, even in the "wide" version. I don't have wide feet. I was trying to replace a 2019 pair of S-phyres. The current wide version is narrower than the standard width from six years ago."
"The vertical height in the toebox is generous compared to some other brands, the strap feels very even and comfortable across the top of the foot, and the heel forms a secure cup shape to reduce slippage. The Wide version could add a few more mm but the material can break in over time. Almost perfect for my wide forefoot yet narrow heel - a combination which is hard to find."
"Genuinely the most comfortable shoe I have ever put on my foot. Just starting to get into road racing after a decade racing XC, and figured I'd invest in high quality shoes. I noticed Shimano had an option for "wide" fitting shoes and gave them a try. Safe to say I am happy with my purchase and have never been more satisfied with a shoe, on or off the bike. I have very wide feet, collapsed arches, and pretty severe pronation that has required two surgeries to help correct, yet these shoes fit me perfectly with the stock insoles in my regular size. I have absolutely no discomfort and no complaints!"
"Very comfortable, easy to adjust, light. Just what I wanted and in the blue. Just as comfy as my old mtb shoes (also in the photo)"
"Great looking and fitting shoes. I have worn Shimano RC-7s for years but I decided to step up to the top tier and got these for my birthday this year."
"Love them!"
"I have a 3E wide foot I have been using the R315 then R320 wide shoes with good success. Unfortunately, they were getting old and worn so I decided to upgrade to the 903E (wide) shoes. I am very disappointed in these. The wide(??) version seems to be quite narrow with a strange fit. I suppose someone with a regular width foot would be happy with these, but I certainly am not. Too bad, I have been using Shimano shoes for quite a few years now but have to look elsewhere to find a wide shoe."
"I have used Shimano shoes for years because they were wide in the forefoot and fit my feet well. But since going to Boa closures they have not fit as well. But now I ordered these advertised as "wide" but they are even more narrow and the foot last has changed from slightly curved to straight. They fit terribly especially for the most expensive non-custom shoes one can get."
