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.
