[Marketing from Salomon, but an interesting read. - Mike]
In 2007, Salomon introduced a classic ski design that received worldwide acclaim due to its ingenious Heel Toe camber. The Heel Toe camber resulted in outstanding performances across the globe.
The key feature of Heel Toe camber is the skis ability to sense where a skier's weight is applied, and not simply how much weight is applied. This ingenious technology has allowed many long times skaters to enjoy classic technique for the first time ever. The consistent and reliable kick benefits everyone from first time classic skiers to the elite Saab Salomon Factory Team classic specialists, who swept the 2008 US SuperTour Nationals.
Here is how it works:
When a classic skier is in the glide phase his/her body weight is on the forward ski, and the weight is greatly concentrated over his/her heel. Even when this ski has the skier's maximum weight applied at the heel, the ski's camber remains off the snow, thus enabling the skier to maintain a long fast glide without drag. To initiate a kick, a skier starts shifting his/her weight forward, from the heel toward his/her toes; when the ski senses the forward shift in weight its camber (kick zone) closes, allowing for an easy and solid kick.
