I think its neato. but is there any practicality? does it work? fischer x-fire boot? anyone have any experience with these boots and their flex pattern?
In their natural, relaxed position, your feet form a V shape.
this position the knees remain parallel when bent. Fischer took these
anatomic facts into account during the development of the Soma-Tec ski
boot and perfected the result. All ski boot models now retain the
natural V-position while the skis are parallel. Neither the feet nor
the knees are rotated inwards. Less force is needed and edge switching
is more dynamic. As confirmed by our World Cup skiers.
