Blue suede shoes are classics that only The King can wear (or sing about). But, Shimano has done us all a favor by making blue (non-suede) mtb/cx/gravel shoes that have knocked it out of the park this year. The Shimano S-Phyre XC9’s are stiff, responsive and great for all things dirt at breakneck speeds.

Dirt shoes to rule them all (for a price)
While Shimano S-Phyre XC9 is a full-gas cross-country race shoe, it would be a shame to pigeon-hole it into that single discipline. With the surge of gravel riding and a renewed interest in cyclocross, the XC9’s should be able to find a home on any bike that likes to ride dirt, fast. That’s exactly what I have done over the entire season. In time, I’ve changed every test gravel and mountain bike to SPD pedals, just so I could ride with the XC9’s. That’s not to say that I couldn’t have changed the cleats to TIME or Crank Brothers (I certainly could have), but I didn’t want to. I just wanted to ride, and pedal swapping on occasion is much easier than cleat swapping. With that, I primarily used LOOK’s X-Track Race Carbon Ti pedals with much success. I had plenty of cleat clearance and the treads never interfered with entry, exit or natural float.
Without any break-in, I went for a 20+ mile mixed mountain bike ride aboard the Trek Supercaliber 9.8. This ride included tons of technical singletrack, a little road and a bunch of gravel roads in-between. Mid-ride, I was in love — and I don’t just mean the blue color — I was floored at the pedal feel and precision the XC9’s offered.
In years past, when barefoot and minimalist shoes were all the rage, I loved the feel they provided, but couldn’t live long-term with their lack of cushioning or support. With cycling shoes, cushioning is largely unnecessary, but support is an absolute must have and that’s something the XC9’s deliver in spades. And, the low stack height provides the cherry on top that yields an on-bike feel like no other shoe. You feel at one with the pedals and can power through anything with precise movements and power transfer.
No question, the XC9’s are a thoroughbred race shoe, but I have loved them for long gravel and road rides aboard the BMC URS 01 and Open UPPER. Likewise, I’ve loved hammering aboard the Trek Supercaliber — one of the finest pure XC racers on the market. Each bike feels like an extension of my legs with the XC9’s providing the connective tissue.
Something unique about the XC9 is the fit of the uppers. Most of the time, a “race” shoe is narrow and restrictive. Shimano has gone away from that and the fit is refreshingly wide and anatomic. It’s noticeably wider than the Shimano RX8 gravel shoe, for example, and allows my feet to spread out in perfect comfort. But, that width is mated to a one-piece, form-fitting upper that’s easily cinched down with the BOA fit system. The upper’s burrito wrap design cradles my feet with perfect, even snugness, thus making these shoes the benchmark in fit and power transfer.
With the BOA IP1, it’s easy to make mid-ride adjustments on-the-fly. Each of the fore and aft dials provide pinpoint fit settings to best cradle your feet. I love BOA dials and find them so intuitive to adjust while in the saddle. A single twist in either direction yields noticeable changes and a simple pop upwards allows for a quick exit. Uniquely, Shimano has chosen to wrap the front cable through a dizzying array of loops — all in an effort to distribute the pressure as evenly as possible. It works fantastically, with both dials delivering even and smooth pressure.
On long climbs, the added stiffness can be felt. As you sprint, all power goes to the pedals. And, on flat or rolling terrain, the XC9’s offer up a rock-solid feel. With all that, your drivetrain receives every ounce of effort you put in. I have noticed that all that stiffness does induce some foot fatigue on long, rough descents. Again, shoes are highly personal, but my feet did tend to hurt after descending for awhile.
The heel cup is worth mentioning. With the external cup (as opposed to a sandwiched design), the uppers remain supple and comfortable and the heel is retained with lockdown precision using one-way fabric that resists upward movement.
Ventilation is excellent. All those bazillion air holes really aid in breathability. My feet have never felt overly hot, but on cold mornings I do feel a slight chill.
Walkability is good and the Michelin outsoles help in that matter. I can walk on my wood floors without damaging them and I can walk, hike or run on the trails quite well. No, these are not going to replace my Hoka One One Torrent 2’s, but hauling my butt through a rough cyclocross course will be a breeze.
- Good overall width for added comfort
- The uppers snug down with wonderful precision
- BOA IP1 dials are winners
- Low-profile design brings your feet closer to the pedals
- Ventilation is great on hot days
- Power transfer galore!
- I experienced foot fatigue on long, extended descents
- That price though
The Bottom Line: Shimano S-Phyre XC9
Many years ago, I recommended that a friend upgrade their road shoes to ones with stiff, carbon soles. After that upgrade, he gave me crap for not letting him in on that little secret earlier. So, for starters, carbon-soled shoes for road, gravel and mountain biking are worth every penny. Now, with the Shimano S-Phyre XC9, that’s a whole lot of pennies, but you won’t find a more capable pair of race shoes

great write-up, thanks! I have wide, not crazy wide feet, but with a problematic protrusion at the base of my fifth metatarsal. Always a problem fit wise, especially on longer rides. My SIDI dominator Megas seem to be just ballooned uppers on the same narrow last, which seems to result in my foot constantly sliding to the outside and pressing on that protrusion relentlessly with every downstroke. Sooo…. thinking of the XC9 S-Phyre in the Wides as a possible (very expensive) solution. From your review it seems like they would offer the right balance of locked in, preventing the sloshing I get now, while being customizable enough fit to accommodate my issue. Thoughts? thanks!
These do offer a nice toe box in their regular widths. I can imagine that wide ones would be even better. Bont also makes shoes with wider toe boxes, but honestly, I didn’t like how they fit otherwise. They could be another option for you.
I have the XC9 in both wide and standard as well as Bont shoes. If you don’t have a chubby wide foot, then the wide Shimano will be pretty sloppy-it’s got the same sole with a higher volume upper attached. Great if you want to use thick socks, but unnerving because you won’t feel as connected to your bike.
Bont offers true wide shoes that have a sole that is wider, but the upper isn’t higher. Since theirs is a bathtub construction you don’t need to tighten the dials so much to keep your foot secure. Plus, their site has a guide that includes both length and width info of all their shoes.
Bont does make great shoes, but the bathtub construction isn’t for everyone. I’ve tried a pair and they just didn’t quite work. One of our other writers did as well with the same results. The upper edges of that bathtub design digs into the side of my feet and the wide toebox (as great as it was) just didn’t make up for that issue.
The standard XC9’s are definitely wide enough for regular folks. Those with extra wide feet may (as you mentioned) still not enjoy the wide XC9’s due to the higher-volume uppers. That said, it’s definitely worth giving Bont a try if you have really wide feet.
I am suffering from morton’ neuroma. For my new gravelbike i have to select pedals/shoes (although i have cranckbrothers mallet e with Nortwave shoes) . Main point: clipless with stiff soles or flats (pedalling innovatios catalyst) wth e.g. Vifeten
Sorry to hear about your food ailment. That doesn’t sound like very much fun. These shoes are wider than other Shimano offerings, but you may also want to consider Bont shoes since they are even wider. My feet don’t really agree with their last, but many people like Bont’s design.
Something to consider about the XC9’s is they are a very stiff outsole. That may be good or bad for your condition. I don’t have much that I could provide to you on either side of that argument. Since they are stiff, my feet do get sore on long descents. But, I can wear them all day just fine (SBT GRVL Blue Course).
Does the flex of the ball of your foot cause additional pain? If so, a stiffer sole might be in order. are you more comfortable in a set of clipless shoes/pedals? Again… that’s a tough call because with that comes a whole host of ankle/knee/hip alignment issues that could cause pain in those areas.
It’s hard for me to recommend really, but those are some thoughts. Best of luck!
