You've seen ballerinas effortlessly walk on their toes like it's no big deal.
But the shoes they wear to sustain their graceful movements from years of intense training are a work of art on their own.
Freed of London is one prestigious factory, and their pointe shoes have been made by hand since 1929.
They're made using a method called turnshoe where the shoes are made inside-out and turned through, which helps protect the stitching.
Their shoes are heavily layered, allowing them to be sturdy but flexible enough for a dancer's movement.
Amazingly, each maker can produce between 30 to 35 a day. As a factory, that's about 4,500 to 5,000 pairs a week.
And next time you see someone do this, you know what went into those magical shoes.
