How to make it easier to dance barefoot?

Well im entering in a pageant, and for talent i am doing a dance to Jar of Hearts by Christina Perry, and i am going to dance with bare feet. Now i have a really sharp turn i really have to ace, any advice besides practice? I practice every day on a wood surface (since that is the stage surface) and wearing dance shoes which i have doesn't look very good with the costume. Is there any... hmm chalk that you can put on your feet to make it ease? i really need some help! Thanks
