How it works:

During down hill skiing the closed heel support fixes the adaptor at the lower position.

During walking the opened heel support provides free rotation of the shoe with minimal friction

"Its like walking in soft boots!"

During walking on moderate hills, the first level of the heel support helps save energy.

Walking on steep hills use the second level of the heel support.
The heel support can be easily switched with the ski-stick between the 3 positions.

On icy surfaces the adaptable ski-crampons provide more sidewards stability during walking. Walking possible with or without  the heelsupport. (The crampons are fixed by a switch mechanism)
