I remember reading somewhere that Edea was started by someone who previously worked with Risport; it might have been something along the lines of the head of Edea is the granddaughter of the man who started Risport (
source 1,
source 2). With that in mind, I would imagine that the boot
last would be similar between Risport and Edea—standard is somewhat narrow, more narrow than C-width Jackson boots at least—so if the Risports fit you well, then Edeas might work for you as well. However, as you've probably already come across in during your research, Edeas are lighter and shaped differently from other boot brands, especially
where the heel is concerned. Since the heel is "shortened," not only will the blade be shorter, but you'd feel taller and maybe even more wobbly than usual when you first skate in them.
For reference, I have previously skated in a pair of Jackson Classiques and now I'm in Edea Choruses. I do like them, especially because they're lighter and easier to maintain (plastic sole and heel means that I don't need to
waterproof them with Sno-Seal), but they leave my feet kind of cold and lacing them is a pain because instead of pulling the ends outward, you do it from the criss-crosses down the center. But as with what DressmakingMomma said, boot choice is a personal decision and people either really love their Edeas or really hate them; just search around The Pro Shop on this forum or The Lutz Corner on Golden Skate and you'll find mixed reviews. So in the end, it's up to you whether you want to stick with your Risports or exchange them for a pair of Edeas. But if I were in your position and like the way the Risports feel, I would keep them until they break down or you've reached a level where an upgrade is necessary. Also, as Edeas become more popular, I would want to be the one rocking a pair of "rare" boots.
