How well your Edeas fit depends a lot on the dealer's skill. Because they don't do conventional heat molds, but require more expert manipulation of fabric shape using a heat gun, and because (last I knew) they come in fewer sizes (no half-sizes) and widths (I don't remember, but I think one width/size) as the other brands of boots, everything depends on the expertise of that dealer.
AFAIK, in the U.S., there is exactly one authorized Edea dealer. He is said to have a high level of technical expertise at reshaping Edea boots. I saw him in person. He said there are strong limits on the extent to which the boots can be resized and reshaped, and that they could not be adapted to my feet. Partly because one of my feet is halfway between two sizes, partly because my toes are substantially wider than my toes, whereas Edea assumes fairly close to uniform width heels, mid-foot and toes.
Think of trying to wrap a single piece of a fairly stiff cloth around an arbitrary complex 3D shape - really not possible. That's a close analog to the limits on reshaping and resizing Edea boots, because Edeas are made from materials like fiberglass cloth and carbon fiber cloth, held together by an adhesive resin. They can soften and manipulate the resin, and to a very small extent possibly adjust the length of the fibers. It is completely impossible to reshape or resize Edea soles.
Most boot technicians lack the expertise to adjust blade offset and alignment on Edea. That's because they don't work with Edeas much, and the mounting technique and materials are quite different than that used on rubber, leather and softer plastic outsoles, more akin to fiberglass roller skates. So if your dealer guesses wrong what offsets or alignment to use with your feet when mounting your blades, and they don't have a high level of expertise, you may be stuck with a bad mount.
On the other hand, Edea boots are fabulously light. People who get a good fit, absolutely love them, and almost never sell them used. I would have loved to be able to use them.
This info was as of about a year or more ago. Perhaps something has changed.
If your Edea dealer has that high level of expertise, maybe he fits other brands of skate boot too?
