I wouldn't call it a gimmick becuase the abducted stance does increase edging ability for every skier so in theory I can see why Nordica and Fischer like the concept. The real question is whether every skier needs to increse their ability to get to the big toe edge on each ski. Bowlegged skiers already have too much ability to get to the big toe edge as they natuarlly sit with their weight over the little toe edge. The slightest move the the iinside creates pressure on the inside edge which can make things difficult.
Yes, clearly for some, abducted boots could be of benefit. Having said that, I am soneone that could benefit from abducted boots, but my alignment is dialed in perfectly with a traditional boot, so clearly abducted boots aren't necessray.
John, I think you said that wrong.? Bow-legged skiers do have their weight over the outside (little toe edge) instead of centered over the ski, but I think they have trouble getting weight/pressure over the big toe edge because they are starting from an unbalanced state? Their kinetic chain is difficult to get balanced over the center of the ski (and wider skis make this worse)?? I think that's correct?
