MK Blades Dance

From the manufacturer:

When it comes to dance blades, look no further than the podiums to make an educated decision. At Pyeongchang 2018, 85% of all Olympic Ice Dance athletes used the MK Dance for its slimline design, allowing the skater to move from one edge to the other much quicker. Essentially, the unique configuration of this blade allows skaters the advantage of employing less body lean to change their edges. It is because of this that the Dance is also worn by the world’s elite synchronized skating teams. This is the choice of champions.
