Seems like there's some concern trolling going on. From what I gathered, Zhenya switched boots after Rostelecom, and those new boots completely broke yesterday. She got new boots yesterday after it happened.
Skaters do not often change their boots. They don't typically have spares because there could be problems with consistency and hurting your feet if you went back and forth between boots. Even if Zhenya had spare boots with her, they would still not be her preferred pair of boots.
Zhenya is a professional. She will do everything she can to make her new boots work. Of course, I hope she can just skate cleanly tomorrow, but most importantly I hope there's no pain because of this.
Such unfortunate timing. We'll have to see how the practices go in a bit.
