I am not a dancer. I bought these from a store 2 years ago while picking up dance shoes for my daughter.At the time, I was stuggling with wearing several pairs of socks with my shoes and boots just to keep my toes warm. These work better than any socks. They definitely add warmth without bulking up shoes or boots. They are also extremely comfortable. Except for a wonderful sense of warmth, I am never aware I have them on. Buy several pair. You wont want to go a day without them.. Also seem to cushion as well.
