Not sure who will be at the top of the leader board Monday or Tuesday. I'll pick Jordan & Lindsey and Viennese Waltz for Monday and Maks and Vanessa salsa for Tuesday's Latin.
I don't get all the problems that everyone is having with their feet. Vanessa. Bindi. Not to mention Meryl's broken toe. And I'm sure others that we don't hear about. I would think that they would prepare their feet, esp. when they're not used to wearing ballroom shoes. If I'm going to do 4 (or certainly 5 lessons in a day) or if it's at a competition, I put double bandaids on all the pressure points on my feet (heel--I use big 2x4 waterproof bandaids, both sides of the widest part of my foot, esp. my little toe, even the top of my big toe if they are closed toe shoes). And even if they're shoes I've already broken in, I wear socks over that for practice. Once you get a blister, it is SOOO painful. And if you toenail is coming off, that's way too much. If I start feeling something new, I immediately put a band aid or two over the spot.
One thing you do notice when you see a live show: dancers often have ugly feet. They are so hard on them. Well, you can't really see the men's feet, but they get blisters, too. I've seen the mail teachers at the competitions, have to work on their feet to patch up blisters.
