Some additional observations: I believe that these are custom race room skis that have slightly less side cut or longer radius that the standard ones.
There is a stamp marked 50m (See photo) on the skis that for the Women's FIS WC standards are in compliance with current regs as being a 50m ski.
It is probably a bit more stable than the standard 45 and perhaps meant for more of a glider course.
Not sure, but just my humble mortal opinion
