The paradigm shift brought about by shaped skis throughout the last decade has been a driving force in the industry; carving skis, twin tips, all mountain skis, powder skis, park skis and for the few still into it, pure racing skis. The transformations have forever altered the topography of skiing. At the outset changes were explosive, radical and all over the place. With the passage of time shaped skis (please, please, please…no more “parabolics!�) have settled into well defined categories and modifications from year to year consist of smaller, more subtle changes in construction, geometry and materials.
The proliferation of ski and binding systems, whether one likes the idea or not, is here to stay and at least in our area acceptance has become less of an issue.
Merging the distinctive character built into each pair of skis and the traits inherent in all bindings into systems that complement one another goes back some time. Salomon started as a binding company that began producing ski boots then skis; marrying the separate components from concept through the design phase into complete systems. Atomic skis, ESS bindings and Koflach boots, consolidated by way of the Austrian government, were also forerunners in this.
It was known early on that certain bindings (the Marker MRR and Look Nevada N17’s up to and including the more recent Look Pivot and Rossignol Axial series) with shorter mounting platforms allowed skis to flex in a smoother, rounder arc. Skis ran faster because ski-to-snow contact was more consistent.
Current systems are put together from the initial concept and design phase and now several companies integrate the bindings into the construction of the skis.
What has all this to do with ski boots?
As elements of a system, the skis, bindings, boots and skier interact with and affect the others. Each piece contributes to the balance of the system; skis have geometry and flex, bindings secure skier to ski, balance retention with release, have a range of elasticity at the heel and lateral travel at the toe and ski boots have different functional characteristics as well as diverse fits.
The skier is the “X� factor in this equation.
Ski boots are the crucial link between two large and opposing levers-skier and skis. The importance of a properly fitted and functionally balanced ski boot cannot be emphasized or reiterated enough.
Boot designs have caught up with the explosion in technology we’ve seen in skis.
Ski boots must do what they’ve always done; fasten the skier to the skis, contain the feet, provide a predictable range of motion and transfer the skiers’ energy to the skis. Several recent factors have altered the way ski boots are designed.
Until the introduction of custom footbeds, insoles, orthotics-whatever you choose to call them, a majority of boots were designed to accommodate a certain amount of pronation. Accordingly there was generally more room on the medial or arch side of the boot for the mid-foot and heel and typically there were far more instances of boots being oversized to allow for the elongation of the feet as they pronated. With universal acceptance that a vast majority of people are going to insert a footbed in their ski boots, boots have become more supportive and tolerances have become tighter.
With the edge angles that can be created on shaped skis the requirements placed on the lateral stiffness of the ski boots is substantial; this along with having to more precisely control what happens with the feet inside the shell. Hence many boots have become more “neutral�…the mid-foot and heel are more vertical-the fit more precise, there is less allowance for pronation. In fact those in the habit of using the articulations of the feet and ankles in a more relaxed fashion many of the newer boots must have “pronation punches� or to be ground in specific areas in order for the individual to do so.
As a result of these requirements, boots now are more functionally efficient. Many boots have taken on the look, feel and functionality of what in the not-too-distant past would have been considered the sole domain of “race� boots.
What this does for the skier is significant; better steering, very efficient transmission of energy to the skis, better feedback and ultimately a much better platform for achieving a good fit.
Several manufacturers are developing ski boots that allow a limited amount of sole flex. Atomic has been at the forefront of this development with Rossignol and Lange now stepping into the fray. This advancement has not been an especially conspicuous talking point or part of any marketing campaign although it’s been an aspect of boot design since the Atomic Beta series shells a few years ago. Atomic is expanding this idea further…see the Atomic page.
This has been written about in past reviews and testimony to the merit of the concept is that other manufacturers are “borrowing� the idea.
Abducted (duck-footed) boot models will increase for the upcoming season. As discussed last season, what this does for the skier is quite dramatic; turn initiation is early and steering the uphill ski-outside edge is more precise. Coming out of turns set up for the next is equally efficient.
There have been reports of “boot out� with this style of shell-in a turn the outside of the foot on the uphill edge of the inside ski hits the snow when tipped up at high edge angles. This then bumps the downhill boot/ski causing an abrupt loss of edge contact on both skis…with the inevitable result; Yeeeeeeha! For the most part complaints have been minimal and there are solutions.
There are some model changes here and there but for the most part things remain status quo.
Boots continue improving in terms of last, liners and the biomechanical attributes of the shells.
