Wrapping my head around it. Sorry to think out loud. So standing neutral, the cable is pulling tension evenly — but since the cable slides in the anchor points, the more you flex your boot, the upper opens vs the lower pulling tighter.
Meaning, it naturally can achieve the buckling mentioned above without need to be preset super tight around the ankle? I think I understand. Will be interested to try a set at some point. Thx for the response.
