Weird tongue design ruins these shoes
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.
Road features in a gravel package
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 ton of wiggle room.
Lightweight SPD shoes
582 grams for pair of 44's, 616 grams for size 45. Stiff in bending and torsion, such that no displacement seen under hand pressure. Tread blocks feel more slippery than the Shimano xc5 Michelin sole, but these rx8's fit my feet better, and are lighter. Size 44 regular fit my 27.5cm by 9.8cm foot best. Has insole arches for high or medium.
Dope MTB shoe!
I would recommend looking at the Shimano RX8 sizing chart to figure out your size (https://imgur.com/HjKBR9B). My Nike 10.5's are 285mm long so that put me in a 45 when I normally wear a 44. Sizing caveat aside, I really like the BOA lacing system, pulling the knob outwards allows you to quickly release the tension and turning the knob to tighten after you get your foot in is quick and convenient. The sole is carbon so really really stiff (also marks easily if that bothers you). On the bike it feels really good. Not so good off-bike though, feels kinda clonky walking around. Better than a road shoe but not as nice as I expected. Overall I would buy again, but if buying from REI, check to see if the XC5 will work for you. Depending on your needs might be enough if just casually riding.
Sizing is off
Far too narrow. I don’t wear wide shoes but may need them for this shoe. Cool shoes but don’t fit as expected.
WAY too narrow.
These shoes look great and feel so light. Too bad they are for tiny feet. I got size 11 and the length is fine, but they are crazy narrow. I could barely squeeze my foot in and if I did a ride, I'd be in pain. Too bad for me. I wanted to like them.
like a glove
a year ago i developed bone spurs on my heals, which caused me to have to take a couple months off riding, partially caused by the rubbing of my previous shoes. I can tighten these into a second skin and have ridden 3000 miles in the past 12 months with hardly any bone spur discomfort.
GREAT SHOE!!
I usually wear a 44 in my cycling shoes but went up to a 44.5 when I ordered these. The fit is perfect even though I usually prefer a wider shoe.
Sizing is Way Off
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 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.
