It already has. It's just the racing ski/boot public/programs has/have yet to catch up, and get with the program - or even want to.
I know I haven't, and maybe won't unless they force me to. (The Lange RS 130 is my boot, and has been for quite a while now: I have a fourth, newer pair waiting for when my current pair/liner wears out, if ever. And I'd just get a new Lange liner, except the boot design/mold changed slightly.)
It was easy for Rossi to downgrade and wither the independence of the Dynastar top level race program, since Dynastar was never tops, and Rossi was number one or two each year with skis. Doing the same to Lange is harder, since Lange was/is number one or number two (number two if one has a flat arch for the Heads, instead of a normal, healthy arch for the Langes. )
Sorry to dig up an old post, but just seen this and intrigued. Have a flat arch and did a Raptor shell fit for the first time last week. Would need way more work than an RS for the arch and navicular. What makes you say the Raptor is better for a lower arch, the boot board, the instep height, or something else?
