Although the Chamber II is known to pedal quite well, it would not be our first choice for all-day slogs or XC flights. Also, while This Is Noteworthy can be great for getting that perfect fit, we prefer Velcro straps and cogs for their quick micro modifications and general ease of usage. But with impressive toughness and defense, and a stiff sole that provides remarkable power transfer, the Chamber II will be well worth its weight for major riders.
6 oz. Superlight and powerful; looks fantastic. Pricey and overkill unless you're a serious XC rider. Giro's Empire VR90 shoe is borderline famous, mixing a tidy, roadway shoe style with comfort and legit trail chops. At $300, you pay a pretty penny, but there's serious performance constructed in: a complete carbon fiber outsole offers it lots of stiffness for toeing the race line, the one-piece upper is downright stunning and helps keep weight in check, and a Vibram outsole makes it surprisingly capable off the bike.
One compromise of the Giro's performance-first design is its snug fit, which is terrific for power-hungry riders but will feel limiting on long, adventure-y days and less serious exploits. And the basic lacing system suggests you trade the quick adjustability of a Boa dial for better total personalization of the fit.
If you don't fall under this category of rider, the Empire is most likely not the finest option for you. Trail, Clipless1 lb. 7 oz. A solid all-rounder with excellent off-the-bike convenience. A little too soft for XC riders. Another big-time gamer in the bike shoe market is Colorado-based Pearl Izumi.
Intended for intermediate riders, trail usage, and off-the-bike exploration, it has the ideal ingredients: a composite shank in the midsole for control, resilient upper product, and decent toe protection that wraps partway around the sides of the foot. You also get an aggressive and sticky Vibram outsolea typical choice for path running and treking shoes.
What's not to like with the mid-range style? Pearl Izumi put a premium on treking convenience, which equates to less rigidity and straight-out power when truly torquing on the pedals (XC cyclists need to steer clear). And riders in flatter areas that do not see major elevation gains (the Midwest of the United States enters your mind) also won't be able to tap into the X-Alp's adventure-ready function set.
