The Merrell Women's Siren Traveller Q2 Mid Waterproof Boots are a durable leather and mesh hiker, engineered for the way women move. Offering superior comfort, alignment and gender-specific support, they are designed with a protective impermeable membrane that locks water and moisture out, alongside a Kinetic Fit™ TRI insole and Q FORM™ 2 insole that is contoured like the foot and features triple zone arch cushioning. Additionally, M Select™ FRESH antimicrobial agents reduces shoe odour to keep feet fresh and an M Select™ GRIP outsole provides expert traction that grips when and where you need it most.
With a suggested temperature rating of warmth down to -10 degrees Celcius, the Celsius R Arctic GTX winter boots pack a real insulating punch for winter cyclists. This performance is made possible by the use of a Koala Gore-Tex® membrane. The fleecy inner face does a brilliant job of trapping heat while the windproof and waterproof membrane prevents cold winds and freezing rain from sapping warmth. 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. NRG Air Carbon-Reinforced Sole The NRG Air carbon-reinforced sole provides the ideal balance of stiffness and comfort. When putting the power down you'll enjoy rapid efficiency but at the same time, a degree of flex adds comfort when you're navigating rougher roads and racking up long rides. SLW2 closure system Keeping the fit snug and comfortable, the SLW2 closure system allows you to dial in the fit just how you like it. The micro-adjust dial gives precise control of the fit but then at the end of a ride, a single button release makes it easy to kick off your shoes. Quick. Simple, Durable. Precise. And in conjunction with the Overlap design, a great fit without pressure points is made possible. Cleat Guidance These Road Shoes are compatible with road bike pedal systems that use cleats with 3-bolt standards, such as: Look Delta and Keo, Shimano SPD-SL, Speedplay Light Action, Zero, X-Series (via 3-hole adapter plate), Campagnolo Pro-Fit, Mavic Zxellium, Time Iclic/Xpresso and Time Impact.

For their Celsius XC GTX winter boots, Northwave have turned to the Gore-Tex Pique membrane to give you an off-road shoe that is both windproof and waterproof. And not only does it keep cold wind and water out, but it also offers an excellent level of insulation against plunging winter temperatures. 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 4-layer insole adds another layer of insulation from the cold, working with the Gore-Tex membrane to deliver outstanding warmth even when you're cycling in cold weather.

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 road shoe and overshoes kit combo and still get cold feet or, instead, enjoy the sleek weather protection of the Extreme R 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 by Northwave, 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 R GTX winter shoes get the stiff and efficient Morph Carbon 12 AAS sole unit. A full-carbon insert at the pedal area imparts outstanding support for a stable pedalling platform while the stiffness rating of 12 out of 15 guarantees direct and positive power transfer, just what you need when building winter miles. 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 Road Shoes are compatible with road bike pedal systems that use cleats with 3-bolt standards, such as: Look Delta and Keo, Shimano SPD-SL, Speedplay Light Action, Zero, X-Series (via 3-hole adapter plate), Campagnolo Pro-Fit, Mavic Zxellium, Time Iclic/Xpresso and Time Impact.
