Yes, in case of fall, if you have the alpine heel the complete release is guaranteed in rotation. The release is effected onto the heel and via the spring box.
Refer to the manual of the setting of releasable system on the spring box: https://www.the-m-equipment.com/images/meidjo/setting-the-releasable-system.pdf
In the event of a frontal fall, the heel will disengage and the telemark mode will be activated. The complete front release is therefore not possible.
