Description

Because gravel is still an emerging segment, some riders find themselves struggling with footwear choices—especially for racing. Mountain bike shoes offer great walkability, but are often too heavy and overbuilt. This leads many riders opting for lightweight road shoes with ultra-stiff soles that boost pedaling efficiency, but the lack of tread is not ideal for the inevitable hike-a-bike sections found in gravel race events and adventurous rides. Shimano addresses these problems by combining the best characteristics of their high-end road and mountain footwear into one shoe that's specifically designed for gravel racing. Lightweight and stiff, but with grippy outsoles and just enough toe flex to be comfortable to walk in, the RX8 might just be the best option out there for dedicated gravel enthusiasts. This wide version provides an alternate fit to best suit your feet.

The RX8 is constructed using a full-length carbon sole that rates at a 10/11 on Shimano's stiffness scale, ensuring hard pedaling efforts are rewarded with maximum forward momentum. The sole is then paired with abrasion-resistant TPU lugs that give you the capability to navigate terrain off the bike without slipping. The uppers are a tough one-piece synthetic with perforated venting that Shimano dubs Surround Structure, offering an good balance of holding power and all-day comfort. The design weighs considerably less than Shimano's flagship mountain bike shoe the XC-9, an impressive feat for a shoe that costs quite a bit less.

  • Featherweight shoes designed for gravel bike racing
  • Carbon composite sole ensures maximum pedaling efficiency
  • Surround Structure uppers provide a comfortable, glove-like fit
  • Wide last provides an alternate fit
  • Lugged rubber outsole adds grip for hike-a-bike
  • Reinforced heel cup for stability under hard pedaling
  • Boa dial and toe strap make it easy to get the right fit
  • Perforations in the upper let your feet breathe
  • Wider cleat-to-pedal interface is optimized for XTR M9100 pedals

    This is a stunning shoe with first-rate fit and finish. Pulling them out of the box, I was like "Wow!" As far as mountain/gravel shoes go, these couldn't be much more like a true road shoe. They're sleek, light, and with a super-tailored (too tailored?) fit. The stiff carbon sole is exposed on the lateral edges of the sole from front to back. Superb heel fit, even better than the higher-end Sphyre mountain shoes. Which, incidentally, I chose after trying them on back to back with these shoes; here's why: 1. On the Sphyres, Shimano has the boa dial on the strappy thing on top of the shoe, which is unusual, but in my experience is better to prevent feeling the dial on your foot. That's exactly my one and only problem with this RX8 -- The dial placement is really uncomfortable and creates a pressure point on the side of my ankle/foot. Deal breaker. 2. These are definitely more of a glove-like fit than the S-Phyres. More tailored, narrow in comparison. This may make them better for you, but I have big daffy duck feet so wasn't ideal for me. 3. I like how easy the S-Phyres are to get on and off with their dual Boa dials. These, with only one, and again, with the dial on the upper instead of the strap, and exacerbated by the superbly snug heel fit, make putting on and taking off the shoes a challenge. But if they fit your foot, these would make a sweet, sweet pair of kicks for gravel racing, or even race day on the mountain bike.

    Do these have the same soles as the non-wide version? Many wides are just extra upper instead of a wider sole.

    lets start with size, i currently have Giant, Giro, Specialized and Shimano shoes that i rotate for different days. They are all different sizes!!! Specialized - 42.5 Giro - 43.5 Giant - 43 Shimano - 44 (only because they don't sell half sizes) Glad i went with a 44 because the 43 would have been too short but the 44 is a tad long in some real thin socks. Width is nice on the wide version and comparable to a nike shoe. Ride - ride feels great. I use these on a TCX that rides all types of terrain from road to MTB specific trails. I was riding road shoes until i broke a road pedal and decided to switch the set up. These shoes feel right at home when putting down power on the road and feel even better when navigating some technical switchback single track. clips are easy to manage and hike a bike sections dont include profanity trying to walk on a road pedal anymore.
