Northwave Celsius GTX boots



Smart winter boots that'll keep you riding through even the coldest UK temperatures

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

The Northwave GTX boots are warm enough to keep your feet comfortable right through the winter.

Let's be clear: my toe game is weak. Bad circulation, bad chilblains, bad luck... just bad. Too often over the past few winters, I've almost sacrificed frozen toes to the cold. So the recent spell of cold weather has reminded me just how glad I've been to have been testing these Northwave winter boots.

The company makes an Arctic version of the GTX, with a thermal lining, that's recommended for use down to -35°C. These, however, are the standard GTX winter boots, designed for temperatures from -10 to +15°C. This seemed ample, and they've been able to take everything the UK weather gods could throw.

The upper is made from Gore-Tex, providing the reliable waterproofing you'd expect from that brand. There are two storm flaps which Velcro-close over the lacing system. The tongue, too, is completely integrated into the boot, so there's very little chance of water seeping in the front. They're certainly sprayproof, rainproof and puddleproof, and they rise fairly high up the leg, which helps to keep rain out and the ankles warm. As with all shoes and overshoes, there's very little you can do against a heavy downpour seeping down your leg via socks or tights. Suffice it to say that these do the job as well as any other method I've tried. And, if your toes do end up wet, the Gore-Tex will keep the wind off and help keep them warm, because that's what matters, right?

Warm they certainly are. I tested them in a 43 (I'm usually a 42/3), on the rationale that it's better to size up and leave room for winter (or even two pairs of) socks. They did come up slightly big, I think, but only a touch larger than expected. I rode them through sleet, a bit of snow, the Rapha Festive 500 and a 160km (100 mile) all-day ride when the thermometer barely topped 3°C. Throughout all that, my toes barely complained once which, it must be said, was something of a revelation.

What's clever, too, is the Speed Lace System (SLS) which is, essentially, a drawstring instead of laces. The advantage of this is that it's possible to tighten, loosen or take the boots off without removing your winter gloves. I had no issues with the SLS at all, and found it kept the boots securely on without any undue pressure - and this was helped by the soft, snug interior.

Why did I choose the SPD-equipped mountain-bike version? Aside from the fact that many of us commute in SPDs, it seemed a wise choice because performance takes a bit of a back seat in the winter,and grip, easy cleaning and ease of walking matter more. The chunky rubber soles inspired confidence, and were easy to clear of mud. The boots dealt with muddy lanes and the occasional field and bridleway, and came out the other side looking good. The midsoles of the Celsius boots apparently have carbon added to the mix for stiffness. It's impossible to say exactly what difference this made, but they were certainly stiff enough; not up to carbon road shoe rigidity, but good.

What didn't I like? I'm quite slender of leg; and the storm flaps could have been slightly tighter round the ankle. But this is a minor gripe. Overall, any product that makes winter riding significantly better is a winner, and these were good enough to inspire me to go out when I otherwise might have just stared out of the window with a cuppa and a biscuit instead. And for that, I reckon they're pretty good value.
