Motivated to Ride Whatever the Weather Riding in the freezing cold, wet conditions of winter is difficult and takes both motivation and the right kit. And when it comes to your feet you can fuss around with your normal off-road shoe and overshoes kit combo or, instead, enjoy the sleek weather protection of the Extreme XC GTX winter boots. Thanks to the Gore-Tex® Duratherm Kelvin membrane, featuring insulating hollow-core fibres, these are shoes that provide you with warmth, rated down to -15 degrees Celcius, total wind protection and reliable waterproof performance. Comfort is superb as the weather turns cold, wet and nasty. At the ankle, the flexible Easyfit Climaflex collar allows easy pedalling but with its Gore-Tex Rattler® membrane also prevents water from getting in. Inside the shoes, the Arctic 4layer insole adds another layer of insulation from the cold - the four-layer aluminium and fleece construction works with the Gore-Tex membrane to deliver outstanding warmth even when you're cycling in temperatures below freezing. Efficient Winter Pedalling It's not just about weather protection though. Pedalling performance isn't overlooked either. Just like the summer version of this shoe, the Extreme XC GTX winter shoes get the stiff and efficient Speedlight 3D Carbon sole unit. A full-carbon insert at the pedal area imparts outstanding support for a stable pedalling platform and quick power transfer. The stiffness rating of 12 out of 15 guarantees direct and positive power application but also a degree of flex for vibration damping. Just what you need when building winter miles off-road. XFrame ® Excellence When it comes to long-ride comfort there's little that matches the snug-fitting XFrame® upper. This innovative design holds the foot firmly in place but does so without creating pressure points. The system is closed via Northwave's own SLW2 ratchet system, allowing precise customisation of the fit, even on the move, as well as an easy release at the end of a tough winter ride. Cleat Guidance These MTB shoes are compatible with MTB pedal systems, which use cleats with SPD standard (2-bolt standard), e.g.: Shimano SPD, Time ATAC, CrankBrothers, CrankBrothers Race, Look MTB, Xtreme MTB, Wellgo MTB, Ritchey MTB.
Northwave Extreme XC GTX Mountain Bike ShoesFrom a long cross-country mountain bike ride to the short intense efforts of a cyclocross race, the Northwave Extreme XC GTX Mountain Bike Shoes ensure superb power transfer. And with their waterproof and insulating Gore-Tex® membrane, you'll be laughing in the face of cold, wet and muddy conditions too. Motivated to Ride Whatever the WeatherIf you're fed up with having to pull on overshoes every time cold and wet weather arrives, and still suffer cold feet, then the Extreme XC GTX MTB Shoes are a fabulous investment for your off-road escapades. Locking in warmth and shrugging off wind, rain and snow is the Gore-Tex® Duratherm Kelvin membrane. This uses hollow-core fibres to give your feet superb insulation from the cold, with Northwave rating it's effectiveness down to -15 degrees Celcius. Wet weather protection is enhanced further by the flexible Easyfit Climaflex collar. This features a Gore-Tex Rattler® membrane to prevent water seeping inside but still allows for smooth unrestricted pedalling. Lastly, the four-layer aluminium and fleece construction of the Arctic 4layer insole provides outstanding insulation, complementing the Duratherm Kelvin membrane perfectly. Efficient Winter PedallingWhile enjoying fabulous comfort you'll also enjoy superb pedalling efficiency too. The stiff Speedlight 3D Carbon sole unit is taken from the high-performance summer MTB shoe. And with A full-carbon insert at the pedal area, you can be confident of instantaneous acceleration and a supportive platform for smooth pedalling. The unit is rated 12 out of 15 on Northwave's stiffness index, meaning there is also built-in flex to soak up vibrations from rougher trails.
