Perfect fit and therefore perfect power transmission

- Kees, 15 May, 2026

This wide version prevents painful outer edges of your foot when you wear your cycling shoes tightly. With the perfect fit and stiff shoe, you transfer power directly to the pedals without loss.

Great cycling shoes !

- Enrico Franchini, 13 May, 2026

These belong very high in the rankings of cycling shoes, in the beginning did a few small rides to feel how they were going to be and they immediately felt tremendously good, even when they were well tightened, then a big ride of 240km and again no trouble anywhere on the feet, Once at km100 I had to accelerate the boas back about 1 turn because my feet swelled a bit and from then on I enjoyed these great Shimano shoes, be sure to measure your foot at the bottom, if it's max 8cm then go for the regular version, if it's more I think you should go for the wide version. Shoe has its price but you also get something for it. Thanks "Mantel" for the turbo fast service !

Very good shoes with no major defects

- Mikael, 11 May, 2026

Second pair of s-phyres never disappointed! I don't have very wide feet, so I'm not bothered by the narrowness sometimes described. Measure your feet carefully in centimetres and follow the Shimano chart, which is quite reliable.

Top shoe.

- Fabien, 23 April, 2026

Don't hesitate to buy one size larger than your usual shoes, just in case, for a quick and easy return.

Fast delivery and good price

- Christian, 28 August, 2025

The cycling shoes from Shimano fit like a glove, but unfortunately the left last presses on my toes, I probably should have taken the wide version, but otherwise perfect workmanship!

Great shoes, stiff sole and snug shoe, great boa closures. I have a fairly wide foot so I took a size up.

Sleek, well-tuned and very comfortable.

- Peter, 21 March, 2025

Top racing shoes! They are tight but adjustable well with the two BOAs, so no pressure points or pain. I took one size bigger (44) than my previous Shimano's (RC300, size 43), length of my foot is 271mm. As far as it matters to the amateur, they are also reasonably light. Plus point: the heel is replaceable, which extends the lifespan.

Nice sleek shoe with super stiff sole

- Cornelis, 23 February, 2025

Fits perfectly for my narrow feet and no extra insole needed as the sole is adjustable to different heights of foot arch.

Great shoe

- Edwin, 16 February, 2025

Nice shoe that in the wide version is also very compatible with someone with hole feet and high instep where the boa closure stays in place and not on top of the foot. Normal shoe size 43 My foot length 273 mm width 25.9 mmm hole foot with high vreef. Got this shoe in only 44 and wide version and fits perfectly.

Pros & Cons

Closes nicely around the foot no pressure points.
Good footbed
Look nice

Quality footwear

- Eric, 12 December, 2024

Comfortable and good feeling, good performance thanks to its rigid sole, top boa tightening and micrometric in both directions and a magnificent look on the foot. I took size 43 like my old giro or scott shoes. Thank you MANTEL, the price is right compared to the competition.

Top shoe with poor finish

- Rudi, 30 May, 2024

One of the best shoes ever bought, for high price you then get poor workmanship,. I hate rain rides, ride 99% in dry weather and after barely 5 months the shoes are already shares entry worn off. Have pair of 10years without damage, I personally find this unacceptable for Shimano shoes of this price range.

Topper.

- Paul, 29 July, 2023

Normally, a wide version of a cycling shoe still falls too narrow for me. With these, the width is no problem. Just see very nice. Also at the heel.

Good fit, poor quality

- Arjan, 14 July, 2023

December 22 bought this shoe and now 10,000km on, but the shoes disappoint me badly for the price. Can speak that I am above average in taking care of my stuff, but the shoe has flaws after only six months. Inner workings are coming loose, nose already damaged when you look at it and the top heel (where you step in) is also starting to crack. Expect better for this money.

Good fit

After countless SIDI shoe models (including Shot) I have now finally found the Perfect shoe.

- Armin, 30 March, 2023

I have always believed to have a Sidi foot. Since the current Sidi Shot me recently has too much volume in the forefoot and the DMT KR SL has weaknesses in heel hold I have the S-Phyre RC903 actually tried out of "desperation". The best shoe I ever had on the foot! I am thrilled and can highly recommend this shoe to anyone with a narrow to medium instep. The brilliant sole shape also makes my Solestar insoles superfluous!
