The skis are "high performance carving" skis (Fischer Progressor 7+). I will be using them for NASTAR and hard snow/groomer skiing (which is by amount, not enjoyment :-(, 95% of my ski days each year)
Anyway, the skis have Railflex bindings, whatever that means.
I had the bindings mounted remotely through ski-depot.com using 317mm as my length, so my last pair of boots weren't used to mount.
As far as the current position with old boots, I just checked and the midpoint is at least ~.5cm forward. It might be more (I didn't measure exactly), so the new boots could ratchet that number up to 1 cm forward.
Would 1cm forward be OK for carving/racing skis?
