Northwave Extreme R GTX – Winter Road Bike Shoes

The Extreme R GTX winter road racing shoes feature the X-Frame® system and overlap construction. An easy and even fit is guaranteed by the SLW2 twist closure system and the new Easyfit Climaflex collar makes it easier to get in.

Warming winter road bike shoes with GORE-Tex: the Extreme R GTX^® from Northwave

The upper has the patented XFrame® and overlap construction: made with the latest innovative materials: it uniformly wraps the foot without any pressure points, helping to transfer every watt of power and eliminating the dispersion of energy and the tingling of the foot ,often caused closure systems that do not guarantee uniform pressure. This is possible thanks to the SLW2 dial, the only one with a step-by-step release that allows millimetric adjustments of the fit on the go, even when wearing winter gloves.

The new Easyfit Climaflex collar combines the extreme flexibility of the Gore-Tex Rattler® membrane with the high thermal insulation of Neoprene, guaranteeing mobility and protection.

The wrapping and positioning of the heel are enabled by an anatomic seat and a solid thermoformed buttress while the Arctic 4Layer insole constructed in Eva + Aluminum + Eva + Pile, ensures greater thermal insulation.

For added safety, the 360° reflective inserts provide amazing visibility on the road.

Sock Tips for Gore-Tex^® Bike Shoes

The sock you put on with your Gore-Tex® footwear is very important. Although highly padded socks can seem like the natural choice to protect your feet from cold, they tend to absorb the sweat produced by the foot, creating an uncomfortable sensation of moisture and wet. This is not related to the shoes, which are completely waterproof. We recommend you to use only reduced thickness socks, made with specific technical yarns which expel the moisture, in order to facilitate the evaporation through the membrane’s breathable pores.

Technologies

X-Frame
X-Frame^® by Northwave is an innovative design, engineered to transfer every watt of power while providing the snuggest, even fit with no pressure points. Totally unique, it combines next-generation materials that are only 0.5 mm thick and ultra soft for exceptional comfort with a structure featuring 360° reinforcements along the length of the foot that connects the sole to the laces via the upper. The result: a snug fit and perfectly balanced closure that pulls evenly around the entire foot from toe to instep. Kudos goes to the innovative route taken by the cable through special tapes: it passes through a complex system of angles and geometric precision made possible purely by relentless testing on countless prototypes. The SLW2 dial closure system works with the X-Frame design, replacing plastic inserts with soft tapes, while the soft, flexible Dyneema cable naturally conforms to the shape of each foot.

BioMap Aero Overlap
Very tightly fitting overlap construction developed according to biodynamic principles. It encloses the foot and ensures a perfect, tight-fitting fit as well as the highest level of support, even and especially in moments of pure power outbursts and tough appearances. And all this without any pressure points. The extremely flexible, custom-fit design also minimizes surface friction for maximum aerodynamic efficiency. Laser-cut micro perforation openings in the inner shoe ensure optimum air circulation

S.L.W. 2
Maximum precision and usability. The side button offers dual functionality: press the button for micrometric release, or lift the button to instantly undo the shoe completely. The ergonomic shape of the ratchet base matches the shape of the foot for added comfort, while the size and minimized weight plus the outer soft-touch covering make it easier and better to grip. It features wires that harness the best technologies used in sailing, and can be easily replaced.
