Choosing a binding

All the different shapes and sizes of cross-country skis call for bindings that match the proportions of the ski and its intended use. They also have to match the brand and model of the boot.

Once again, the industry is not the best friend of either the consumer or the retailer. As bad as it was with Rottefella's cheesy NNN system duking it out with Salomon's more solidly made and better supported SNS Profil and Pilot systems, things got worse when Rottefella convinced its manufacturing allies to adopt the NIS plate that only accepts an NNN binding.  While a mounting method that requires no jig and no drilling eliminates most of the problems that made NNN so failure-prone, it also eliminates consumer choice in an obvious move to monopolize the market.

To make matters worse, Fischer and Rossignol decided to stab Rottefella in the back and introduce their own plate, the IFP, that excludes Rottefella bindings and cannot be drilled to mount a Salomon binding on top of it at all. With many -- perhaps most -- skis coming with either a Sin plate (NIS) or the even more heinous IFP plate, consumer choice gets funneled down to just what a couple of manufacturers are willing to provide. These decisions are made by accountants, not by skiers.

Fortunately, the IFP binding takes a regular NNN boot. We haven't quite returned to the System Wars of the 1980s.

Salomon offers their skis pre-drilled to accept any of their own bindings. They also sell an NNN-compatible boot and binding system for skis without a plate. As always, Salomon's version is much better made than anything produced by Rottefella's manufacturing partners. This keeps a shred of choice left in the marketplace for consumers who want or need to mix and match. 

But wait, there's more. 

If you have chosen a moderately heavy ski, perhaps with a metal edge, you will have better control with a beefier boot and binding. The only heavy system binding widely available is Rottefella's NNN-BC. You can get boots for NNN-BC ranging from something slightly heavier than a regular touring boot up to some gnarly models with buckles and external cuffs designed to drive and control the new generation of shorter, wider off-track skis. This is still well short of the state of the art in downhill-oriented backcountry skis. Telemark equipment has reinvented the alpine ski,  making the free heel aspect of the turn completely irrelevant. 

You can still find boots for heavy 75mm bindings.  These were generically referred to as three-pin, even though some models had no pins at all. Some cable bindings used a slide-in toe piece with a fixed bail. If you really plan to take touring skis more than a couple of miles from where you parked your car, use 75mm bindings and boots. They're a proven workhorse. If you prefer touring in semi-refined environments like snowmobile trails, then the NNN-BC system will allow for somewhat more fluid striding -- at least as fluid as you'll get with a chunky BC boot sole. 

It gets tricky on skis that barely reach the threshold of heavy, such as the Fischer Spider 62. Available either as a flat top or with a SIN plate, Spiders are easily skinny enough to use in a set track at a touring center. But the metal edge on the Spiders makes them a trifle heavy for the cheapest and lightest touring boots and bindings. If you don't push the skis very hard,  you might not notice any control problems, but then what was the point of buying a ski with a metal edge? When you jam on the emergency brake, you want it to dig in. Salomon's two-bar Pilot binding gives a lighter boot more lateral control than a basic single-bar binding would. If you're looking at metal edge skis 62 to 70mm wide, choose the Pilot binding or a BC system binding. If nothing else, make sure you get a manual binding rather than an automatic step-in if you go with light touring boots on a ski like that.

It's disheartening to see the suppliers of the cross-country ski industry fighting over market share like a couple of street dogs scrapping over a half-eaten carcass in an alley.  Economic competition does not necessarily favor a better product, only a better marketed product. I guess they all control a ski better than a leather strap across the toe of an elkhide mukluk. In the modern era, it's not about getting large numbers of people to enjoy the physical and emotional benefits of an activity. It's about getting the largest number possible to spend the largest amount of money on it.

Skis for a beginner

Cross country skiing used to be simple. In the interest of making it simpler, the industry has made it vastly more complicated. The rack has filled up with perfect tools for specific subsets.

When I got into the activity in 1984, all this complication was just over the horizon. With a fairly wide conventional touring ski, a kick wax that was not quite right but basically adequate, and a detailed vocabulary of profanity, I was able to decipher the basics. At every plateau on the climb to develop the skills that interested me, I was always able to curse my way to the next level.

In the early 1990s, Fischer introduced little bitty skis for adults. The first of these was a skating ski just 147 centimeters long. It allowed skiers to try out the V-stance of skating in trails that were not widened and groomed for it, as the skate technique gained acceptance. From that one ancestor sprang all the shorties that we see today.

The initial micro ski went extinct quickly because of its many shortcomings. The ski industry is famous -- or should be -- for solving one problem while creating several others. This is not just planned obsolescence marketing. It is a genuine lack of understanding in the ski community of how their stuff actually works. It may be the same in other activities, but, because skis have almost no moving parts, they seem to nurture a simple-mindedness that permeates the culture. It's even worse in lift-served skiing, because those skiers are only going in one direction.

Because cross-country skiers propel themselves over flat ground, and climb hills, the design of the ski is a little more complicated than for a ski designed only to steer under the influence of gravity. Thousands of years ago, when cross-country skiing emerged as a means of winter transportation in northern Eurasia, people were probably less demanding. They wanted to stay on top of deep snow, and be able to move themselves along. Various things attached to the bottom of ancient skis, like horsehide, and seal skin, and patterns cut into wooden bases, indicate that they didn't like to wax any more than modern skiers do. But they did use sticky natural substances as part of the general tool kit. It was all about getting from place to place.

The genius of the cross-country ski is the glide. You get something for nothing. It takes less energy to slide on snow than to walk on dry ground. It takes way less energy to slide your feet in the motion of skiing than it does to slog through deep snow in bare boots, or to trudge on racquet-type snowshoes. And with skis on, you can get the advantage of sliding even on snow so shallow that you don't really sink into it much with bare boots.

Ski length may have been determined by regional variations in snow type and depth, and perhaps a bit by superstition. "Reach up" provides a ski that is about 115 to 120 percent of your height. For general purposes, this is a good proportion for classical striding on a traditional ski. But flexible boots, and bindings that only hold the toe, make any ski tricky to steer on downhills. That situation inspired the development of patented bindings that have ridges on them to engage the bottom to the boot, and shorter skis that can steer more easily when gravity will not be denied. What's not to like?



Shorter skis do not stride as well. A skier who starts on traditional length skis and practices all the ways and wiles that have evolved for centuries will have a much better intuitive grasp of how to make a ski obey, and when to use one of the modern shorties instead. The skier who starts on a short ski and never questions it will be at the mercy of the industry to solve any dissatisfactions. A whole set of skills becomes unnecessary until you -- by chance -- get into a situation where you would have liked to know something you didn't even know existed.

With all this specialization at your disposal, you can pick a ski that suits you right now and enjoy it for years. That is the benefit of all that variety. If you are an athletic type who thinks that the skate technique is all you will ever want to do, you can buy that equipment and take those lessons and never bother to learn the traditional style. The techniques are quite different, for all their deceptive similarities. Likewise, if you know you're only going to shuffle around on a few weekends a winter, get the ski that makes it easiest.

When I'm standing with a beginner at the ski rack, we both have to gaze into a crystal ball. I don't want anyone to throw down a few hundred bucks for a package that is not going to serve them well for many years. Sometimes people just want to do it, bim bam boom. I'll take the money. But if a skier wants more detailed advice, I owe them that. Moreover, I owe cross-country skiing that. It's a great activity with many facets. Oversimplification does it no justice.

Skiing is full of unspecific terms. "Wax" refers to substances that span the range from liquid through paste, sticky solid, and brick-hard, applied to ski bases in whole or in part, by smearing, crayoning, or ironing, to provide glide or grip or both. "Back country" refers to anything from the local park to the far side of Denali. To the resort-oriented ski industry, it's anything they're not preparing with large machines for consumption by paying customers. Here's your ski. It says "BC." Have fun and don't break a leg.

Your skier of ancient times could take a variety of terrain in stride. Racing skis were skinnier, with a stiffer central section to pull the grip zone off the snow in the glide phase, but anyone not afflicted with the neurosis of racing would have a fine time on their mid-width touring ski, whether the trail was groomed to the primitive state of the art or an unbroken blanket of magical white. If things were icy, or gloppy, or chunky, everyone would have a uniformly crappy time, and laugh about it. But you had to be willing to work with your equipment. Now you can have an extensive quiver of near-perfect skis, if you can afford them. Your main challenge then is to pick the right one for the trip you intend to make that day.

I suppose that, in the time when skis were made by some local guy in the village, some skiers would have a couple or three different pairs if they could. Your supply chain was nice and short. You could ask the maker for exactly what you wanted. Now you have to shop around for brand and availability and take advice from people who might not even use the product. The 20th Century development of downhill-only skiing took over the public image of the sport so that cross-country skiing seemed like something invented by hippies in the 1970s as a goof. Cross-country product is manufactured and imported by companies whose accounting departments have the final say in what hits the stores. The stores and other retail outlets order based on what they think will sell. In the industrial world, your menu is provided by people who don't know you, taking their best guess.
