Why We Like The Shimano RC903 S-PHYRE Cycling Shoe

Built specifically for road racing, the high-performance Shimano RC903 S-PHYRE Cycling Shoes are engineered to get you to the finish line with unmatched speed, power, and efficiency. The upper of the shoe is wrapped in 360Âş reinforced micro-fiber leather with perforated venting, allowing for excellent breathability, and is secured with dual BOA Li2 dials for quick adjustments, minimal pressure points, and a snug fit to your foot. DYNALAST technology reduces fatigue on longer rides by keeping your foot securely in place, while an anti-twist heel cup adds stability to the heel as you apply max power to the pedals during a breakaway or field sprint.

New favorite biking shoes!

Familiarity:
I gave it as a gift but have feedback to share

I bought these as a gift for my partner who has brand loyalty to Specialized. But as soon as he put them on, they were the most comfortable bike shoe he had ever tried and now after he's ridden over 500 miles in the past month, they still remain the most comfortable bike shoe! Doesn't hurt that the blue is his favorite color. The toe box is smaller, closer to the design of the old Specialized biking shoes.

Fantastic road shoes!

Familiarity:
I've used it several times
Size Bought:
45.0

Fit, look, comfort, stiffness, function, color (black), ventilation, all excellent. I especially like the dual BOA fasteners and the replaceable heel. Plus, these are usually pretty expensive, and still are expensive, but I got a great discounted price here.

Better Than Expected

Familiarity:
I've used it several times

You'd expect a great shoe for this price, but I still had my reservations. The shoe was initially stiff but has broken in nicely. It remains exceptionally light and responsive.

Very narrow - had to return

Familiarity:
I returned this product before using it
Size Bought:
46

These are very narrow. They do have a wide version but it appears they don't make those in a 47 which is what I would likely need. As such, I did not wear them to ride so I can't give that feedback. One feedback from a design perspective is that the solid base doesn't extend the entire length of the shoe such that the soft material is exposed in the middle of the shoe. If you had the luxury of only using these for racing that's not a problem but I would be using these for daily training as well and as such walking a bit is necessary. I would worry about the durability in that regard.

Great Rode Shoe

Familiarity:
I've used it several times

Lives up to hype - lightweight, good fit without insert as I have high instep, carbon increases pedal power and took 1/2 size smaller than my SIDIs.

Nice Shoe - Too Narrow

Familiarity:
I returned this product before using it

Shoe is well made but too narrow if your foot runs wide. The adjustability of the dials is nice and allows the user to get a precise fit.

Comfort and Performance

Familiarity:
I've put it through the wringer

First time purchasing a Shimano road shoe so I didn't know what to expect. True to size length wise, but the toe box seems really roomy to me. For me that was both good and bad. Good because it makes the shoe more comfortable in my opinion, and bad because with the stock insoles I was constantly tightening the dials to try and get a really snug fit. Eventually went to insoles that took up more room and that solved my problem. Really like the adjustment dials as you can really fine tune the fit and it's easy to do while on the bike.

Great shoe and fit

Familiarity:
I've used it several times
Size Bought:
US Size 10

purchased after having numerous issues with Fizik and other brands that were too tight. The fit is great and comfortable over long rides. Good arch support and the boa dials allow for perfect adjustment and easy to do on rides. The feeling of the power transfer is the biggest improvement over my previous entry level carbon shoes.
