Ah, I misheard it, she says "Kirilenko's running barefooted" as you say. I guess that's part of Kiri's warm-down program after matches. Yes they say barefoot running is good to train your feet (and that's the whole marketing idea behind the vibram and nike free etc). I know what your voice sounds like now
Juggling as part of her warm up? Lol. Maybe they think it'll keep her relaxed.
