I'm looking for used GS-skis and Fischer skis tend to pop up. They come with freeflex bindings that has a connection between heel and toe piece. The bindings have between 5-7mm delta.
The problem is that i don't like huge binding deltas. I have boots with lots of forward lean (salomon falcon) and relativly thick calves. It works well with 0-2 mm delta, but does not play so well with 5mm or more delta. Would it be possible to put a 5-7 mm shim under the toe piece or do the toe and heel need to be in the same plane because of the freeflex connector?
And how does this freeflex thing work? Seems a bit counter intuitive at first that locking the distance between the toe and heel can promote free flex. Can the heelpiece slide fore aft freely and the boot size is kept constant by the freeflex connector?
