You can’t buy direct from Edea though, they don’t sell through their website. On their website they even show brio and motivo wothout blades, and those definitely come as a set with blades. So i guess for overtures it depends which dealer you buy from, but most i found when i was looking (this was a few years ago) sold all the lower level boots (the first three edea models) already mounted.
That's interesting because no where I know of sells them pre-mounted. Boot only. And this is all over the world.
