RC903 S-PHYRE Cycling Shoe - Men's

Extra Watts

Literally the stiffest shoes that put the PRs down! Light, and powerful my heal doesn’t move it’s locked down for pure power transfer!

Great feel!

I've put it through the wringer

I bought my first S-Phyre pair 4-5 years ago. Just bought my second pair. Same feel and comfort. BOAs are smoother to operate (or maybe because my old ones were cruddy?). I'm sold on this shoe.

These shoes rock!

Super light, great BOA mechanism, no heel slip - worth the money

Great road shoe, love it.

I'm really liking the Shimano RC903 S-PHYRE shoe. I have been a long time Sidi shoe guy for road and mountain. This is the first non Sidi shoe I've purchased in past 15 years and I have to say these shoes are equally as nice and fit me really well. I'm very happy with how well the shoe feels, the heel cup lock in is great, no slippage and the fit is excellent. The BOA dials are easy to use and quick, can really dial the tension in on your foot. I found the shoe to be true to size. I'm wearing the standard width 45.5, the same size as all my Sidi shoes. I tried the Lake CX239 (very nice shoe) shoe as well but found the fit for my foot not as good as the Shimano.

Great road cycle shoe

I've used it once or twice and have initial impressions

These are awesome cycle shoes. The fit, comfort and stiffness is fantastic

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.

Great, comfortable, stiff shoes. Decent room in toe box for average foot. Narrow heel with good hold.

Fantastic road shoes!

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

I returned this product before using it

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.
