RX8 Mountain Bike Shoe
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.
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.
