The SNS Wedge is a Salomon innovation that allows skiers to enhance the efficiency, power and length of each skate stride. It is lightweight plastic insert that is mounted under the binding, raising the front of the foot by 5mm, tapering back down to 1mm at the heel.
The Wedge increases the skier's ankle flexion, thus allowing for a more powerful beginning of each skate stoke - In other words, by increasing the angle at your ankle, the ski 'squirts' ahead, up the hill (or ahead), increasing the 'free-glide' feeling.
The SNS Wedge can be mounted under SNS bindings only.
