I've been looking at higher-resolution photos that I found via Google and Yahoo's news photo search.
Here are two pix from Tarvisio:
And here's a more profile-oriented shot from World Championships in Garmisch:
My thoughts? It's tough to tell whether she's back on the Rossi-via-Lange plugs again. The switch back would entail, beside the painting of the shells, a swap of buckle hardware, cant-joint hardware, etc. Could they be re-badged Rossi/Lange plugs? Certainly. And if they are, the job that Head did is masterful.
The other thought is that Head my have commissioned a pair of boots from Lange, using Head's plastic dye to color match Head's own product, and allowing Head to do all drilling/routing of buckles and canting equipment in-house. That makes some sense.
This reminds me of when Hermann Maier, in his final years when he was with Head, started the season on Head's boots then gradually switched back to his tried-and-true Langes when he found that the Head boots weren't working right for him. In that case, though, Maier was very open about the mid-season switch.
