These models are fitted with an Up&Down lift (TSL patent) to reduce the effects of walking uphill and downhill (the back of the binding passes under the frame to keep the foot flat and prevent it from pressing against the toe of the shoe). The binding allows you to put the snowshoe on quickly, precisely, and comfortably, and it memorizes the size of your shoe. Finally, the 8 crampons, the front teeth, and the grips under each foot provide maximum traction.
