Just recently saw this picture, but it's kind same thing for all photos like this

Are this boards really so huge or this is photo/marketing trick?
If they ride with full quiver kites in almost perfect conditions would't be easier for them to use smaller boards?
Does boots here play it's role, is it easier to pop & land with so massive boards? Probably yes for landing, but complicated freestyle moves looks like much harder with big boards.
Cheers everyone
