Chan seems to have worn Edea Concerto rather than Fly recently (Hanyu in those?) http://cdn3.volusion.com/zarbv.ethpz/v/vspfiles/photos/categories/388.jpg?1384070403 .
Figure skating seems a bit out of step with modern boot technology, having people flying around with their poor little feet incased in pounds of leather while hockey, speed & various inline skating disciplines have long since moved on to using newer materials.
This may be because figure skating involves a great deal of angular momentum which the other sports you mentioned don't have. If the boots are not high enough on the leg (speed skates) then there's not enough support, and if they're too bulky (hockey skates) then it's hard to get the crossed leg position, and if they're too stiff (inline) then you run into issues of spiral fracturing the ankle and leg up on landing.
You'll note that roller, which has angular momentum issues as well, also sticks to figure skate style boots.
Just a theory.
