Barely... by just .04 seconds over Petra Vlhova.
That's strange because Vlhova's L cuff alignment is clearly way off... don't know about footbeds or cants. As a result:
1. she's A-framed with skis non-parallel at the top of every L footer;
2. she has to drive her L knee in to put the ski on edge; therefore
3. at the end of L footers there's a delay in transferring to her R ski while she pushes her L knee back out where it belongs.
This has to cost speed. So why did Shiffrin win by so little?
