A lot of the kids and adults have moved to EDEA at my rink. Wide variety of the different boots. Many seem to be happy with them. The one thing most people say is that because the heel height is different, that takes some getting used to (especially on spins). Others find them noisy until they find the new balance spot. I was skating with a friend of mine on the very first day she got hers and she was definitely noticing a lot of differences from her previous boots (Harlick). In addition to finding them noisy, she felt like there was pressure over the middle of her foot that hadn't been there in any other boot. But, she was also able to do turns she normally had trouble with.
The biggest complaint I've seen is that they break down fast. Usually what happens is the kids get the boot their "supposed" to get, or even one level lower because that's what was recommended for their level. They trash those in a matter of months. Then, when they get new boots at a level up from the prior boot, they are better and last longer. This was a big problem for some of the kids around regionals that were duct taping their skates because they were so broken down.
