290:, make carved turns possible at low speeds and with short turn radius. Skis had sidecut since they were first carved from wood – typically around 5mm on a long ski. But it wasn't until the early 1980s that much deeper cuts were explored. In 1979 Head developed the "Natural Turning Radius" concept and skis with 7.3mm sidecut (~35 m radius). Olin Corp developed a teaching ski with an 8 m radius (31mm sidecut) and the first asymmetric ski, with no up hill cut and, because side cut involves proportionately wide tips, a platform for the boot to allow a very narrow waist. A total of 150 pairs were produced.

left ski and one right ski. The inside and outside lines of the ski were different, being "asymmetric" to compensate for the shorter distance the inside ski had to cover compared to the longer one for the outside ski. These skis exhibited amazing carving speed in giant slalom when used properly. A couple of years later, Atomic copied the concept and created their own ski called "Differential". Although these skis would still win races today, they were not used to their full potential as nobody used them as they should be.

previous standard for slalom skis and a tight, 15–m turning radius. It took eight of the top ten places in its initial racing, allowing skiers to stand with a stronger straighter leg and make the desired carve. In the US, ski instructors found that students could easily make parallel turns that would otherwise take considerable practice and training. The company put the ski on the market in 1993 as the

parallel turns. Carving maintains the skis efficiently turning along the direction of travel as opposed to skidding at an angle across the direction of travel. For a given velocity, carving with shaped skis typically requires less effort than stemming or parallel and offers increased speed and control in even steep descents and highly energetic turns, making it ubiquitous in racing.

unnecessarily heavy tips and tails. Increasing widths held snow contact constant as lengths and turn radius plummeted. The necessary tip and tail mass as well as carved edge contact made 180 cm skis as stable as straight skis 20% longer. Design challenges such as engineering increased stiffness to keep wide tips from bending over bumps and in deeps continued to be met as

The rider is using pressure, twist and tilt to get only the side of the board into the snow. Then engaging the sidecut edge which determines the carved turn shape. This type of turn causes the board to bend and store a large amount of

the slope, as opposed to a path straight down, reduces the skier's speed. The skier wishing to go slower must wait a little longer before initiating the next C-turn, making the "C" longer. This will lead the skier to ski more across the slope (in extremes uphill), reducing the average path slope angle.

The ski is made with a side-cut radius. This is the radius of a circle that would fit into the shape of the edge of the ski if viewed in plan-view. This is approximately the maximum radius of turn that can be cleanly carved. Expertly used skis are capable of carving clean circular arc segments whose

Unlike a skidding turn, which primarily uses the skidding effect to reduce speed (hence the "Z"-path), a (perfect) carved turn does not lose any speed because there is no braking action in the turns. Rather, the reduction of the average path slope angle resulting from the skier's S-shaped path down

Kneissl, struggling in bankruptcy released a radical 19–mm sidecut ski for a radius of 14 m. In tests, Elan found that its skis substantially boosted skier capability. Engineers experimented and were funded at Atomic, Blizzard and others. With cuts of 20 mm, short skis were a necessity to avoid
300:
engineers Jurij Franko and Pavel Skofic experimentally adjusted sidecut and developed a physical model—desired radius, speed, forces and lean one could generate, and bend the ski to solve for this combination. By 1991 they released a ski with a sidecut that was, at 22.25 mm, three times that of

Prior to the introduction of "shaped skis" in the 1990s, the technique was not simple to learn. Since then, it has become accessible and carving is commonly taught as a form of parallel skiing alongside the classic parallel "brushed" technique. Modern downhill technique is generally a combination of

Starting a carved turn requires the ski to be rotated onto its edge, which can be accomplished through angulation of the hips and knees applied to both skis, leading them to efficiently carve a naturally parallel turn. Carving turns are generally smoother and longer radius than either stemmed or

In 1990 Volkl released their metal "Explosiv" with a 10-mm sidecut and 28-m turn radius. K2 introduced a 10mm sidecut race ski, whose improved edging and turning ability became a sought after by consumers. Volant released a 12mm cut ski in 1992, followed by
Dynastar, and K2.

Recreational skiing is usually done at speeds in range between 5 m/s and 15 m/s with average turn radius of less than 15 m. Accordingly, sidecuts of modern recreational skis are calculated for turn radius of approximately 7 to 15 m.

Carving typically involves the skier making a series of "Cs", or half circles, down the hill (with two consecutive "C"s forming an "S"). Skidding turns on the other hand would rather follow a Z-shaped path.

Skis bend when edged (angling of the ski running base to the snow surface). Combined with sidecut, this creates a curved interface to the snow, and at a turn of that radius, the ski carves, rather than
