Gravel Riding. With Extra Velocity. While some may like to take it easy and others love a gravel race, the RX8 SPD cycling shoes are definitely focused on that speedier end of the gravel riding spectrum. This race-inspired focus is ably demonstrated by the use of a super-stiff carbon composite sole, ensuring all your watts are efficiently transferred to the pedals with little waste, letting you crush gravel roads at speed. The sole unit also features stripped back TPU lugs, reducing overall shoe weight while still maintaining sure-footed performance when you're off the bike. With their two-bolt MTB pedal compatibility, you're also assured of the best pedalling efficiency and stability as you zip from gravel to road and back to gravel again. Dynalast Design x BOA IP1 Precision Adjustment The upper of the RX8s is a one-piece synthetic leather construction, wrapping the foot snugly and holding the foot stable as you pedal - it delivers all-day comfort and performance in equal measure. Shimano's DYNALAST design conforms to your foot shape to eliminate hotspots and it ensures you have natural and smooth pedalling motion, even across rough terrain. Next comes the BOA IP1 dial technology - this allows you to customise the fit precisely to your foot and to spread pressure evenly and comfortably, even on the fly. With 1mm of micro-adjustment, you'll always be able to get the fit just how you like it. Lastly, with Silvadur antimicrobial inner soles you'll also finish the day with fresh feet, no matter how intensely you've been riding. If your cycling thrills come from speeding along gravel roads, maybe even looking to race, then the RX8 SPD Shoes are the shoes to turn too. Remarkably light and super-stiff, these shoes will soon leave competitors eating your dust.

Buying shoes is difficult. These are great shoes, stiff, well built and comfortable, but narrow and thus long for its size in this style. Knowing which last Shimano uses is impossible unless one is replacing the exact shoe from a year before. I tried on 3 different lines of shoes in a shop, each fit is different. Honestly, if I'd had the chance to try these before buying I'd have bought others. But, I'll be riding these for the season, as there's no opportunity to try on all the types to find last that actually fits.

I had really high expectations for the RX800's. I've been using Shimano ME7's for 2 years and I absolutely love them. I really like the design of the RX800 and the overall concept. Unfortunately, the fit was a tad large and they were a bit uncomfortable when I first tried them. After a bit of break-in, they became tolerable and eventually pretty comfortable. These things are stiff, so I was excited to replace my roadie shoes/pedals and go with something more capable in off-road settings. The first time I struck a root, the cleat stripped clean out of the bottom of the shoe. This left me limping home with one foot clipped-in. I was able to re-install the cleat using the second set of bolt holes and I believe I'll still get use out of these. All said, I have never had ... MoreI had really high expectations for the RX800's.

Just ordered my 2nd pair of these shoes after 1.5 years on the first pair which are still very useable after extensive use but showing wear on toes.Regarding size chart, I use footwear in the 11.5 to 12.0 range (US). I wear size 46 for my Sidi road shoes and Specialized MTB shoes. No way my foot fits into a 46 for the Shimano RX8. But the 48 is great!Pros: Great comfortable fit (these shoes feel great!), excellent power transfer, feet never fatigue or get too hot (e.g., 90+ degree rides in the Sonoran desert). The shoe is a perfect interface between my foot and the pedal.Cons: On occasion when having to hike my gravel bike through deep, soft sand (like this morning), said sand readily infiltrates through the ventilation holes!

I am a bit disappointed with (what I perceive as premature) wear at the base of the toe but these shoes are not used on a road bike where they would never see a rock!

My pair of RX8 size 41s with cleats fitted weigh 576Gms. My equivalent size 42 Shimano M089 MTB shoes weigh 855Gms. That's a saving of 279Gms - 33%, or 1/3rd! I have no need for the full MTB design, but I do want a sole I can walk in to visit cafes. So these are perfect. The weight saving is noticeable when turning the pedals; maybe someone could do the maths to calculate the energy saved on a 50 mile ride? As I'll keep the size 42 MTB shoe for winter riding with thicker socks, I initially chose the size 40, but it was too tight. Now Shimano make a wider fitting (Apparently only in black?), but it seems we can't get it here in the UK! So I ended up returning the size 40 for size 41s. I have to say comfort and fit is excellent; but I'd recommend using a shoe-horn as ... MoreMy pair of RX8 size 41s with cleats fitted weigh 576Gms.

The silver bling is very smart; but if I were to buy the larger size for use with winter socks, then it would have to be black!
Wide cycling shoes is a relative term. My 20 year old Shimano shoes were in very rough shape and my son grabbed my 5 year old replacements (this says a lot about Shimano durability). The RX 800’s sounded perfect for my current riding, gravel, back roads and XC mountain biking. Out of the box, these shoes looked narrower than my beaters ( but were at least 3 oz lighter, per shoe! Once I figured out how to loosen them and get them on my feet (it was a bit of a struggle), I was hooked.These shoes have a thin, yet well structured upper with a perfectly stiff sole. The bottoms are excellent with good traction and no cleat scratch as I walk. Clipped in, I feel more direct transfer of my effort to the peddles than I have ever felt before. The lacing system can be ... MoreWide cycling shoes is a relative term.

The lacing system can be tightened or loosened on the fly.While these are not a perfect fit for my wide, feet (ranging anywhere from 44-47, 10.5-11.5 US) I have found the right socks to snug in my heel while giving me the space at my toes. I don’t really care about how my shoes look, but these are pretty snazzy in a subtle way.I hope the shoes hold up as well as my last two pairs.
I wear regular 12 US and ordered these in regular 47. It is my first pair of Shimanos. The sole is super stiff and makes me feel like I have thighs I don't have. The fit is good -- the heel cup is deep, the length seems spot on, and the toe box is wider than I expected based on the euro-fit associated with Shimano. I have not used the extra arch inserts but may give them a try soon. The strap at the metatarsals actually does something but is not noticeable when walking or riding, and it and boa straps allow easy loosening if your feet swell on a ride. The black camo looks matte black from a distance but adds a bit of pizzazz when you get close up. The only potential con I see is with early sole markings after a few gravel rides and walks and trying to adjust to the ... MoreI wear regular 12 US and ordered these in regular 47.

The only potential con I see is with early sole markings after a few gravel rides and walks and trying to adjust to the cleat position -- while it is good there are lot more options to position your cleats than on my Mavic Crossmax, the tread is closer together so it not as easy to "find" your cleats when clipping in and I missed them a few times. That said, I'm learning to lean into the whole "if you are going to use it, it is going to show wear" idea with bikes and bike gear.
These are very nice and almost too nice for off road shoes!The RX802's are very much like a road shoe in that they are lightweight, stiff and also fairly narrow fitting; not a problem for my feet but anyone with a wider foot should be aware. On the subject of fitting the sizing is typical of Shimano shoes I've had in the past i.e. they come up small. I'm a 44 in most brands but sized up to a 45 and that is fine with a bit of space in the toe box to allow for thicker socks. A 44 would have definitely been way too tight owing to the shape of the shoe and it's narrow design.A nice touch which I appreciated is that they come with interchangeable arch support pieces in the box to tailor the fit a little bit.

This is an over-looked area with cycling shoes and so many have thin, flat insoles which lack any support and have a negative effect on bike fit.I should mention I've seen some reviews mention about walking and the shoes being a bit unstable, but though they are very stiff this has not been my experience. However, if you are looking for a shoe that is suitable for frequent 'hike-a-bike' action or extended walking off the bike (touring perhaps), I'd say these are possibly not the shoes for you.I like these shoes and though I wouldn't use them in the off road slop of winter (too nice for that!), they are so much nicer than wearing MTB shoes on my gravel bike. In fact, if I could only have one pair of decent cycling shoes to use across road and gravel set-ups, I'd choose these... so long as they were in a sale with a big discount as mine were!
6K miles on my first pair, and now I’m onto my second pair. They are lightweight and stiff like a road shoe, yet lightly lugged like a XC shoe (no toe spike mounts though). Great for power transfer, light hike-a-bike, town stops, etc. I use these bike packing as my all-day shoe including in camp.Bi-directional Boa dial is awesome. You can precisely adjust tighter AND looser while in the fly. Many other shoes in this class only have uni-directional Boa.TPU sole is a bit slippery on slick/polished interior surfaces, but perfectly fine on concrete and dirt. Be careful on stairs!Fit is a personal thing. For me it’s great and fits like a glove. No slipping, no crushing. I think there is a wide version out there, but yes this is a narrow road style shoe without a ... More6K miles on my first pair, and now I’m onto my second pair.

I followed the size chart to the letter, wound up with a size 45. Upon receiving the shoes, the shoe was waaay too long. Like 2 sizes too long. It wasn't close enough to go "oh well" and deal with. At least an inch and a half of extra shoe. I bought these specifically due to having the 20% off coupon available and am really bummed to have wasted that savings on these. I obviously haven't used these enough to know, but I noted that the inside tongue rubs against your foot in a weird way since it subducts under one side and sort of "wraps" your foot. So there's only contact with the tongue on one side. At first it was quite painful to wear but that seemed to go away once the shoe "settled". So that may or may not be a problem. I wondered if that rubbing would cause ... MoreI followed the size chart to the letter, wound up with a size 45. Upon receiving the shoes, the shoe was waaay too long. Like 2 sizes too long.

I wondered if that rubbing would cause blisters over time. My Bontrager shoes' tongue is a normal design and it feels natural on the foot, but with these it's like one side of the foot has extra pressure on it due to the design. Could be nothing, I'm not sure. More use would tell.I bought these to use when commuting and road-biking because i wanted to clip-in, but also needed the ability to walk easily. SPD SL cleats never seemed to offer much benefit and I only use SPD. These shoes seemed to have a really nice, stiff sole and clipping in/out was smooth even with the added tread. I was really happy with the look, the tread, and the stiffness. It almost felt like walking in a normal shoe. They did not feel heavy. Such a shame the sizing is so off that I can't use them.I really want to love these, but we'll see if I can get the sizing right. I'll give them another shot with a new size. These are pretty narrow as well, so if you have wide-feet don't even bother. They widen up a bit when you wear them but as someone with wider feet i could instantly tell these are very narrow shoes. More narrow than my bontrager cycling shoes of a smaller size.*Note: on every other website, these shoes come with cleats. REI doesn't seem to do that, not a dealbreaker but worth noting. Buy cleats if you need them. They did come with neat arch supports you can choose to use or not, i thought that was a nice touch.
Sizing runs a little short, though width is standard. The tongue is weirdly connected to the shoe's uppers on both sides, which makes getting into it a bit more work than is typical. That tongue arrangement also makes the shoe rather uncomfortable; sometimes I could fidget with it enough to make it reasonably comfortable -- but then, during a ride, I would always end up feeling it again. I want cycling shoes that "disappear,' meaning I don't notice them at all. These are not those shoes, at least for me.On the plus side, they are light, stiff, and nice-looking. But comfort rules, and these aren't comfortable for me.
